Check Digit Verification of cas no

The CAS Registry Mumber 245526-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,5,2 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 245526-90:
(8*2)+(7*4)+(6*5)+(5*5)+(4*2)+(3*6)+(2*9)+(1*0)=143
143 % 10 = 3
So 245526-90-3 is a valid CAS Registry Number.

A convenient and facile synthesis of O,O-diphenyl 1- (5-alkyl- 1,3,4- thiadiazol -2-yl) amino-1-arylmethylphosphonates

Lu, Shui-Ming,Chen, Ru-Yu

, p. 3443 - 3450 (2007/10/03)

Nineteen novel O,O-diphenyl 1-(5-alkyl-1,3,4-thiadiazol-2-yl)amino-1- arylmethylphosphonates were synthesized by the three-component condensation reactions of 2-amino-f-alkyl-1,3,4-thiadiazoles with triphenyl phosphite and aromatic aldehydes in the presence of acetic acid.
