Check Digit Verification of cas no

The CAS Registry Mumber 127680-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,8 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127680-77:
(8*1)+(7*2)+(6*7)+(5*6)+(4*8)+(3*0)+(2*7)+(1*7)=147
147 % 10 = 7
So 127680-77-7 is a valid CAS Registry Number.

A Study of the Photochemically Induced Electron-Transfer Reactions Between Pyridinedicarbonitriles and Primary and Secondary Aliphatic Amines

Bernardi, Rosanna,Caronna, Tullio,Poggi, Gabriella,Vittimberga, Bruno M.

, p. 903 - 908 (2007/10/02)

A study on the photochemically induced electron-transfer from primary and secondary aliphatic amines as donors to pyridinecarbonitriles as the acceptor is reported.A comparison between the substitution positions and the spin density distributions, obtained via teoretical calculations using the 6-31+G basis set, shows some discrepancies, and forms the basis of a hypothesis on the mechanism of the reaction.
