Check Digit Verification of cas no
The CAS Registry Mumber 127395-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,3,9 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127395-20:
(8*1)+(7*2)+(6*7)+(5*3)+(4*9)+(3*5)+(2*2)+(1*0)=134
134 % 10 = 4
So 127395-20-4 is a valid CAS Registry Number.

Substituent effects in the bis(benzotriazolylmethylation) of aromatic amines
Katritzky, Alan R.,Rachwal, Stanislaw,Wu, Jing
, p. 446 - 455 (2007/10/02)
1-(Hydroxymethyl)benzotriazole and aromatic amines react to give an equilibrium mixture of N-mono- and N,N-bis(benzotriazolylmethyl)arylamines.Electron-releasing substituents on the arylamine ring shift the equilibrium towards the N,N-bis(benzotriazolylme
