Transition to the Web Version of SciFinder

CAS plans to complete the transition of eligible commercial and government customers to the Web version of SciFinder® .

Nearly all of our customers have made the transition to the Web version, and we are committed to ensuring that all customers have the best SciFinder experience possible. We recognize that some organizations are in the midst of browser or operating system upgrades, and we are eager to adjust our planning, if needed, for your particular organization.

If your organization:

  • Can transition to the Web version of SciFinder by your deadline, no additional action is required on your part.
  • Would like to transition to the Web version of SciFinder before the deadline - or -  if you would like to use a custom "Message of the Day" in the SciFinder client to promote your organization's transition, follow these instructions.

You can help your colleagues in this transition by:

  • Directing them to this page for more information about the transition.
  • Informing them of the many advantages of the Web version of SciFinder, including:
    • Experimental procedures - to make better synthetic research decisions faster
    • Bioactivity and target indicators - to gain greater insight into the early stages of biological discovery efforts
    • Markush searching - to perform preliminary IP assessment
    • SciPlannerTM - to identify alternative approaches for designing synthesis pathways 
  • Downloading and distributing a promotional flyer (~936K PDF).

You can request additional promotional materials by email.

For any other questions, please contact your SciFinder Sales representative or the CAS Customer Center.
