Check Digit Verification of cas no

The CAS Registry Mumber 116907-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,0 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116907-39:
(8*1)+(7*1)+(6*6)+(5*9)+(4*0)+(3*7)+(2*3)+(1*9)=132
132 % 10 = 2
So 116907-39-2 is a valid CAS Registry Number.

Anhydrides as Acylating Agents in Lipase-Catalyzed Stereoselective Esterification of Racemic Alcohols

Bianchi, Daniele,Cesti, Pietro,Battistel, Ezio

, p. 5531 - 5534 (2007/10/02)

A new enzymatic method for the resolution of optically active alcohols from racemates is reported.It involves lipase-catalyzed esterification in organic solvents, with acetic, propionic, or butyric anhydrides as acylating agents.Lipase Amano P, from Pseudomonas fluorescens, adsorbed on Celite 577, was employed as stereoselective catalyst.Under these reaction conditions, the enzyme is not chemically modified by the anhydrides.A number of primary and secondary alcohols have been obtained in high optical purity by this procedure.
