SciFinder "Classic" Interface Retirement - July 31, 2022

On July 31, the University of California's access to the "classic" SciFinder interface will be retired. SciFinder-n (or SciFindern), which was introduced in 2020, will be the only SciFinder access going forward. With the launch of the new interface, CAS halted further development on the old interface to focus on continual updates and enhancements to SciFinder-n features and functionality, and they will sunset the classic SciFinder in the near future. Here’s a quick overview of SciFinder-n.

  • If you are already using SciFinder-n, you don’t need to do anything.
  • If you are still using SciFinder classic, start using SciFinder-n. You do not need to register for a new SciFinder account; your account credentials will work with both interfaces. Any bookmarks will automatically redirect to
  • If you are new to SciFinder (either version) and want to use it, you will need to register for an account using your UCSD email address. Start at the UC SciFinder registration site to begin.
    • Make sure that VPN is running ( when you go to this page from off campus. It's required to complete the registration process, as well as regular use.
    • SciFinder-n is restricted to current UC Irvine faculty, students, and staff. 

To learn more about SciFinder-n, CAS has a very good collection of training tutorials and webinars. If you have questions about accessing or using SciFinder-n, or want to set schedule training for yourself, a class, or research group, please contact Mitchell Brown (

SciFinder-n, from CAS, is one of the core databases for chemistry and related sciences, including biochemistry, chemical engineering, materials science, nanotechnology, environmental science, physics, mechanical engineering, health sciences, and more.

  • It indexes 58 million references from journal articles, patents, conference proceedings, and more, AND 194 million chemical substances and 70 million protein and nucleic acid sequences, AND 145 million single and multi-step reactions.
  • You can:
    • Look up chemical substances by name, registry number, or structure/substructure (using the SciFinder editor or running from within ChemDraw). Then look up property data and spectra, identify commercial suppliers, or find reactions or references related to that substance.
    • Look up chemical reactions by structure or substructure. Run a retrosynthesis plan to explore pathways to develop synthetic plans.
    • Search for articles, patents, and conference proceedings by keyword, author, organization and more, for relevancy-ranked results


CAS will be discontinuing the client platform on June 30, 2011 for all U.S. and Canadian academic institutions. After June 30, 2011 UC Irvine will only have access to the web version of SciFinder.  Click here to register for your SciFinder Scholar web account (restricted to current UCI faculty, students, and staff).

February 22, 2011


CAS has investigated, confirmed, and addressed a compatibility issue involving the SciFinder structure drawing editor and Java Version 6 (JRE 1.6), update 24 released on February 15. This new Java version is now compatible with the web version of SciFinder. Customers who upgrade to Java Version 6 (JRE 1.6), update 24 will no longer experience any loss of SciFinder functionality. Various earlier versions of Java 6 have also been re-tested and verified as fully functional with the web version of SciFinder.

As always, if you have follow-up questions or any issues related to our product or Java support, please contact our technical support team at

Subject: Java 6, update 24 and SciFinder

We've just become aware of a potential incompatibility issue involving the SciFinder structure drawing editor and Java Version 6 (JRE 1.6), update 24, released by Oracle on February 15, 2011. The issue affects only the web version of SciFinder on the Windows operating system. Customers using SciFinder 2007, SciFinder Scholar 2007, or the web version of SciFinder on a Macintosh OS are not affected.

To prevent any negative impact to your SciFinder experience, we suggest that users of the web version of SciFinder on Windows delay installation of Java Version 6, update 24. We are fully engaged in identifying the source of this potential issue and will update you further when we have more information.

If you have questions, please contact our technical support team at 800-753-4227 (option 4) or at

Thanks for your attention and patience.

Update on Macintosh v10.6 Snow Leopard and SciFinder Scholar

August 31, 2009               Jim Corning, CAS

CAS is committed to SciFinder support for major upgrades to key operating 
systems and we test these systems to ensure that they work optimally with 
our products. Testing of the web version of SciFinder with the newly released 
Mac OS X 10.6 (aka Snow Leopard) is currently in progress. We are happy to 
report that preliminary testing has not revealed any significant issues; 
however, if significant problems should be identified CAS will provide customers 
with an update. 

In regards to JRE versions, Snow Leopard comes with Java SE 6. This is not a 
new version and was previously supported in Mac OS X 10.5. No significant 
issues have been identified in preliminary testing using Java SE 6 with Mac OS X 10.6.
