133448-53-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133448-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,4 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133448-53:
(8*1)+(7*3)+(6*3)+(5*4)+(4*4)+(3*8)+(2*5)+(1*3)=120
120 % 10 = 0
So 133448-53-0 is a valid CAS Registry Number.

Facile Synthesis of 1,2-bis-(Cyanomethyl)benzenes
Poulton, Gerald Arthur,Boulet, Camille Andre
, p. 3347 - 3353 (2007/10/02)
3-Alkoxy-1,2-bis-(cyanomethyl)benzenes can be prepared in two steps, in high yield, from m-alkoxy-N,N-dimethylbenzylamines by directed metallation followed by ethyl chloroformate-promoted cyanide displacement.
