100 Millionth Small Molecule Added to CAS REGISTRY

08. July 2015

On June 23, 2015, an important milestone was reached in CAS REGISTRY - the registration of the 100 millionth small molecule. Because most novel chemistry is now disclosed in patents, it should come as no surprise that this substance was first introduced in a patent. Coferon, Inc. of Stony Brook, NY reported a novel therapeutic designed to treat acute myeloid leukemia in its international patent application (WO 2015081280) dated June 4, 2015. The new molecule was assigned CAS Registry Number 1786400-23-4.
