Accessing SciFinder-n

SciFinder-n is the updated version of the popular SciFinder platform. As of April 1, 2020, it is now available for use by Northeastern students, faculty, and staff. Search journal articles from Chemical Abstracts and Medline, the CAS Registry, chemical reactions, predicted and experimental properties, synthetic preparations, and patents.

If you are already a registered user of SciFinder, you can connect to SciFinder-n with your current SciFinder username and password - no need to create a new one. If you do NOT already have a SciFinder username and password, you can register using your Northeastern email. PLEASE NOTE: After registering, you will receive an email confirmation of your registration. If you are completing new user registration off campus, please use this proxied link instead of the one you receive in your email confirmation.

Why do I need to register if I have access through Northeastern?

You will need to create an account (see New User Registration) and accept the CAS SciFinder Terms of Use in order to use the database:
