Check Digit Verification of cas no

The CAS Registry Mumber 90072-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90072-45:
(7*9)+(6*0)+(5*0)+(4*7)+(3*2)+(2*4)+(1*5)=110
110 % 10 = 0
So 90072-45-0 is a valid CAS Registry Number.

TRANSFORMATIONS OF SUBSTITUTED 5-AMINOPYRIMIDINES UNDER CONDITIONS OF THE DIAZOTIZATION

Nemeryuk, Michal P.,Sedov, Andrej L.,Safonova, Tamara S.,Cerny, Antonin,Krepelka, Jiri

, p. 215 - 233 (2007/10/02)

Reaction of nitrous acid with 4-substituted and 4,6-disubstituted 5-aminopyrimidines Ia-In produces 4-substituted and 4,5-disubstituted 1,2,3-triazoles IIa-IIv, resp.Under similar conditions, 2,5-diaminopyrimidines XIIa-XIId give N(7)-oxides of 2-amino-4-aralkylthiopyrimido-1,2,3-triazines XIIIa-XIIId, and 5-amino-4-chloropyrimidines In and X give 2-diazocyanoacetamides XIa and XIb, resp.Also described are syntheses of 5-formylaminopyrimidines XVa-XVg from glycine ethyl ester via sodium salt XVI.
