Troubleshooting SciFinder Problems

  1. Login Failed: SciFinder is not authorized for use from this IP address.  
    If you receive this message, it means your computer's IP address has not been authenticated as an Emory IP.
    Try to log in using this link:
  2. Structure Editor slow?  The SciFinder structure/reaction editor can be slow to load in your web browser especially if it is the first time it has opened during a session. You may also be prompted to accept a certificate or ActiveX plug-in.  A Java plug-in is also required for the editor; although, it generally is already installed.
  3. Make sure you are using a supported operating system and web browser and have installed plug-ins.  To review the recommendations, see the SciFinder System Recommendations and Requirements. 
  4. If you have problems with your account that cannot be resolved by resetting your password, you must contact CAS directly: 800-848-6538 or The library does not have access to user accounts.    

Please contact the Chemistry Librarian -- Chris Doty [ ] -- for ongoing access problems.
