Check Digit Verification of cas no
The CAS Registry Mumber 132635-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,3 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132635-67:
(8*1)+(7*3)+(6*2)+(5*6)+(4*3)+(3*5)+(2*6)+(1*7)=117
117 % 10 = 7
So 132635-67-7 is a valid CAS Registry Number.

N-2-Pyrimidylarylamidines (2) obtained by the reaction of 2-aminopyrimidines (1) with aryl cyanides in the presence of anhydrous aluminium chloride have been converted into 2-aryl-1,2,4-triazolopyrimidines (4) by oxidative cyclisation in the presence of lead tetraacetate.
