Check Digit Verification of cas no

The CAS Registry Mumber 258330-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,3,3 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 258330-06:
(8*2)+(7*5)+(6*8)+(5*3)+(4*3)+(3*0)+(2*0)+(1*6)=132
132 % 10 = 2
So 258330-06-2 is a valid CAS Registry Number.

Fusions of pyrido[4',3':4,5]thieno[2,3-d]pyrimidines with N-heterocyclic moieties

Ahmed,Sensfuss,Habicher

, p. 1119 - 1122 (1999)

Versatile 2-thioxopyrimidine-type building blocks ethyl 3-(2-ethoxy-2- oxoethyl)-4-oxo-2-thioxo-1,2,3,4,5,6,7,8- octahydropyrido[4',3':4,5]thieno[2,3-d]pyrimidine-7-carboxylate (4) and ethyl 4-oxo-2-thioxo-1,2,3,4,5,6,7,8-octahydropyrido[4',3':4,5]thieno[2,3- d]pyrimidine-7-carboxylate (8) were synthesized from diethyl 2-amino-4,5,6,7- tetrahydrothieno[2,3-c]pyridine-3,6-dicarboxylate (1). Derivatives of linear and angular heterocyclic systems having the imidazole and 1,2,4-triazole ring were obtained from the key intermediates 4 and 8, respectively.
