Check Digit Verification of cas no

The CAS Registry Mumber 838841-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,8,8,4 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 838841-71:
(8*8)+(7*3)+(6*8)+(5*8)+(4*4)+(3*1)+(2*7)+(1*1)=207
207 % 10 = 7
So 838841-71-7 is a valid CAS Registry Number.

Candida Rugosa lipase-catalyzed kinetic resolution of β-hydroxy- β-arylpropionates and δ-hydroxy-δ-aryl-β-oxo-pentanoates

Xu, Chengfu,Yuan, Chengye

, p. 2169 - 2186 (2007/10/03)

A simple and convenient method was reported for the preparation of optically active β-hydroxy-β-arylpropionates, δ-hydroxy-δ- aryl-β-oxo-pentanoates and their butyryl derivatives via CRL-catalyzed hydrolysis. The optically active products are potential precursors of some chiral pharmaceuticals and natural products.
