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.
