Check Digit Verification of cas no
The CAS Registry Mumber 109671-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,7 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109671-53:
(8*1)+(7*0)+(6*9)+(5*6)+(4*7)+(3*1)+(2*5)+(1*3)=136
136 % 10 = 6
So 109671-53-6 is a valid CAS Registry Number.

Synthesis of the potent mutagen 3,5,8-trimethyl-3H-imidazo[4,5-f]quinoxalin-2-amine.
Nyhammar,Grivas
, p. 583 - 587 (2007/10/02)
The mutagenic title compound (5,8-DiMeIQx) was synthesized by two different routes: from 2-methyl-4,6-dinitroaniline; and from 4-chloro-2-methyl-6-nitroaniline. The latter and more convenient route involved 2,1,3-benzoselenadiazole intermediates.
