Check Digit Verification of cas no

The CAS Registry Mumber 872357-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,3,5 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 872357-79:
(8*8)+(7*7)+(6*2)+(5*3)+(4*5)+(3*7)+(2*7)+(1*9)=204
204 % 10 = 4
So 872357-79-4 is a valid CAS Registry Number.

Preparation of functionalized primary chiral amines and amides via an enantioselective three-component synthesis of propargylamines

Gommermann, Nina,Knochel, Paul

, p. 11418 - 11426 (2005)

A general preparation of functionalized primary chiral amines and amides from propargylamines has been developed. The chirality is established by an enantioselective three-component reaction of an aldehyde, a terminal alkyne and a secondary amine in the p
