Check Digit Verification of cas no
The CAS Registry Mumber 5581-52-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5581-52:
(6*5)+(5*5)+(4*8)+(3*1)+(2*5)+(1*2)=102
102 % 10 = 2
So 5581-52-2 is a valid CAS Registry Number.

Kochergin,Aleksandrova,Korsunskii,Shlikhunova
, p. 182 - 184 (2000)
We have synthesized a series of novel 2-amino-6-(nitroimidazolyl)thiopurines by reaction of thioguanine with 1-alkyl(1,2-dialkyl)-5-chloro-4-nitro-,2-alkyl(1,2-dialkyl)-5-bromo-4-nitro-, and 1-alkyl(1,2-dialkyl)-4-chloro-5-nitroimidazoles.
