About CAS Full Text Options

CAS Full Text Options, or CAS FTO henceforth, provides scientists and information professionals with links to full-text electronic documents from a large and growing group of scientific publishers, subscription agents, patent offices, and patent document services.

CAS FTO is provided free of charge through a collaboration of scientific journal publishers, Chemical Abstracts Service®, FIZ-Karlsruhe, and the Japan Association for International Chemical Information (JAICI).

 

How Does It Work?

The full-text options for the document you requested are generated at the time of your request. You may see a screen that asks you to wait "One moment please" while links to the options are being generated.

Documents may be available via the following full-text options:

The full-text options available vary from document to document, depending on the journal, patent country, publication year, and other factors. CAS FTO uses your IP Address to verify your journal subscriber status with some publishers.
