Check Digit Verification of cas no

The CAS Registry Mumber 762272-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,2,2,7 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 762272-97:
(8*7)+(7*6)+(6*2)+(5*2)+(4*7)+(3*2)+(2*9)+(1*7)=179
179 % 10 = 9
So 762272-97-9 is a valid CAS Registry Number.

The resolution of important pharmaceutical building blocks by palladium-catalyzed aerobic oxidation of secondary alcohols

Caspi, Daniel D.,Ebner, David C.,Bagdanoff, Jeffrey T.,Stoltz, Brian M.

, p. 185 - 189 (2007/10/03)

The palladium-catalyzed aerobic oxidative kinetic resolution of key pharmaceutical building blocks is described. Substrates investigated are relevant to the enantioselective preparation of Prozac, Singulair, and the promising hNK-1 receptor antagonist from Merck. The latter provides the most selective aerobic oxidative kinetic resolution yet described.
