Check Digit Verification of cas no

The CAS Registry Mumber 137422-10-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,2 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137422-10:
(8*1)+(7*3)+(6*7)+(5*4)+(4*2)+(3*2)+(2*1)+(1*0)=107
107 % 10 = 7
So 137422-10-7 is a valid CAS Registry Number.

Easy Direct Stereo- and Regioselective Formation of β-Hydroxy Nitriles by Reaction of 1,2-Epoxides with Potassium Cyanide in the Presence of Metal Salts

Chini, Marco,Crotti, Paolo,Favero, Lucilla,Macchia, Franco

, p. 4775 - 4778 (1991)

A simple efficient, anti stereoselective, and highly regioselective method for the synthesis of β-hydroxy nitriles by the direct opening of 1,2-epoxides with KCN in acetonitrile, in the presence of metal salts, is described.This new method appears to be competitive with the other methods previously reported. Key words: β-hydroxy nitriles; epoxide opening reactions; regioselectivity; catalysts.
