Check Digit Verification of cas no

The CAS Registry Mumber 352555-60-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,5,5 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 352555-60:
(8*3)+(7*5)+(6*2)+(5*5)+(4*5)+(3*5)+(2*6)+(1*0)=143
143 % 10 = 3
So 352555-60-3 is a valid CAS Registry Number.

Synthesis of thieno[3,4-d]pyrimidines by the reactions of 3-amino-4-carbamoylthiophene derivatives with 1,3-dicarbonyl compounds

Ryndina,Kadushkin,Solov'eva,Granik

, p. 1879 - 1885 (2007/10/03)

The reactions of ethyl 3-amino-4-carbamoyl-5-methylthiophene-2-carboxylate with 1,3-dicarbonyl compounds were studied. During the reactions, the corresponding ketone is eliminated to give ethyl 5-methyl-4-oxo-3,4-dihydrothieno[3,4-d]pyrimidine-7-carboxylates.
