Check Digit Verification of cas no

The CAS Registry Mumber 21601-05-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,0 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21601-05:
(7*2)+(6*1)+(5*6)+(4*0)+(3*1)+(2*0)+(1*5)=58
58 % 10 = 8
So 21601-05-8 is a valid CAS Registry Number.

Su, Guifa,Qin, Jiangke,Ni, Qingling,Mu, Hongtao

, p. 2429 - 2435 (2003)

Tartaric acid was transformed into imidazole-4,5-dicarboxylic acids 2, then via esterification, hydrazinolysis, condensation with aromatic aldehyde in glacial acetic acid to furnish seven title compounds in about 24% overall yield.
