Chemistry: SciFinder-n
Resources for library research on chemistry-related topics.
About the Transition
CAS SciFinder-n includes all the content of "classic" SciFinder along with new features and enhanced functionalities. "Classic" SciFinder will be discontinued in December 2021.
- Do I need to make a SciFinder-n account?
If you already have a SciFinder account through LSU, then you can log into SciFinder-n with your current SciFinder login/password. If you've never used SciFinder at LSU, you will need to register for an account. - What about my alerts and saved searches in Classic SciFinder?
You can import most SciFinder saved answer sets and Keep Me Posted alerts to SciFinder-n. Learn how to migrate answer sets and alerts. - Can I migrate my SciPlanner files to SciFinder-n?
Unfortunately, no. You will need to download your files to your own computer by selecting the Workspace tab in SciPlanner, then Export.

-
CAPlus File (Chemical Abstracts)Updated daily, the CAPlus file contains titles, abstracts and indexing for journal articles, patents, dissertations and much more.
-
CAS Registry File (Substance Information)The CAS Registry file contains over 155 million unique chemical substances and more that 68 million sequences. You can find names and synonyms, property and spectral data, preparation methods, and commerical availability with a link to articles or patents in other files that contain it.
