Check Digit Verification of cas no
The CAS Registry Mumber 129075-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129075-89:
(8*1)+(7*2)+(6*9)+(5*0)+(4*7)+(3*5)+(2*8)+(1*9)=144
144 % 10 = 4
So 129075-89-4 is a valid CAS Registry Number.

Benzotriazole Mediated Synthesis of Methylenebisanilines
Katritzky, Alan R.,Lan, Xiangfu,Lam, Jamshed N.
, p. 341 - 346 (2007/10/02)
Methylenebisanilines and methylenebis(N,N-dialkylaniline)s are prepared by the reactions of 1-hydroxymethylbenzotriazole with anilines and with N,N-dialkylanilines under acidic conditions.Isolation of the intermediate 4-(benzotriazol-1-ylmethyl)anilines and the N,N-dialkyl analogues and their reactions with anilines allow the efficient preparation of both symmetrical and unsymmetrical members of both product classes.
