Check Digit Verification of cas no

The CAS Registry Mumber 127845-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,4 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127845-08:
(8*1)+(7*2)+(6*7)+(5*8)+(4*4)+(3*5)+(2*0)+(1*8)=143
143 % 10 = 3
So 127845-08-3 is a valid CAS Registry Number.

OXIDATION OF 1-AMINOBENZIMIDAZOLES. SYNTHESIS AND PROPERTIES OF 1,1'-AZOBENZIMIDAZOLES

Pozharskii, A. F.,Nanavyan, I. M.,Kuz'menko, V. V.,Chernyshev, A. I.,Orlov, Yu. V.,Klyuev, N. A.

, p. 1241 - 1253 (2007/10/02)

1-Amino-2-R-benzimidazoles are oxidized by lead tetraacetate to give, depending on the substituent in the 2-position, either to 1,1'-azobenzimidazoles (R=H, CH3, C6H5, Cl, N(CH3)2) or 3-R-benzo-1,2,4-triazines (R=NH2, NHCH3, NHC6H5, OH).The factors affecting the course of the reaction are discussed.The physicochemical properties of the 1,1'-azobenzimidazoles obtained have been examined.
