SciFinder-n & Chemical Abstracts: Home

About This Guide

This guide lists detailed information about accessing, troubleshooting, and training for SciFinder, the end-user online version of Chemical Abstracts. SciFinder is the most important resource for finding chemical information.  

I am indebted to Teri Vogel at the University of California at San Diego for allowing me to use her excellent guide as a template.

SciFinder Mobile - New

Access SciFinder from your mobile device: author, keyword, chemical name/RN searches.

With SciFinder Mobile you can:

  • find references to published research for a topic of interest
  • find information on a substance of interest, including nomenclature, molecular formula, and properties
  • find references to published research from a scientist or company of interest 

You cannot:

  • Draw structures.
  • See the complete Registry records or CAS references.
  • Link out to article text.
  • Create new answer sets or Keep Me Posteds.
  • Limit, analyze or refine searches, see cited/citing references, etc.
  • Mark, email or otherwise save any references of interest, or any other “synching” between the mobile and regular web versions.


Login to SciFinder


USA is now providing access to the Scifinder-n platform!

The links on our Databases page now link to SciFinder-n. If you have saved answers and alerts (Keep Me Posted) you should migrate them from the old SciFinder to SciFinder-n. Click the Bookmark icon   to access the migrate feature found on the Saved Answers page 

SciFinder answer files exported to an external drive in the .akx file format must be imported and saved to SciFinder before they can be migrated to SciFinder-n.

New to SciFinder?

Register for access : users must register with CAS *from an on-campus computer* and receive a login name and password.

Who can use SciFinder

SciFinder is restricted to USA faculty, staff and students. Unlike most of our other electronic resources, there is no walk-in access available for non-USA affiliates on any library computer.

There is a pay-as-you-go online version for non-USA end users. See the Chemical Abstracts tab for details on these options.
