Since April 1, 2023, in addition to the traditional CAS SciFinder, services such as CAS Formulus and CAS Analytical Methods have become available on the same platform. Your login ID and password are shared with CAS SciFinder. 

Starting from late August 2025, enhanced features have been introduced, including "AI-powered search capabilities (SearchSense)". (Details)

■ Overview

A comprehensive platform that provides workflow tools for research in chemistry, science and technology, and life sciences.
