Check Digit Verification of cas no

The CAS Registry Mumber 134650-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,5 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134650-54:
(8*1)+(7*3)+(6*4)+(5*6)+(4*5)+(3*0)+(2*5)+(1*4)=117
117 % 10 = 7
So 134650-54-7 is a valid CAS Registry Number.

Synthesis of 1,2,3,4-tetrahydro-4-oxothieno[3,2-d]pyrimidine and perhydropyrimidine derivates from alkyl dicyanoacetates

Neidlein, Richard,Sui, Zhihua

, p. 579 - 584 (2007/10/02)

Nucleophilic addition of methyl 3-aminothiophene-2-carboxylate (2) as well as of β-alanine ethyl ester (11) to one CN group of the salts 1 of alkyl dicyanoacetates, followed by cyclization, yielded 1,2,3,4-tetrahydro-4-oxo- thieno[3,2-d]pyridimine derivat
