Check Digit Verification of cas no

The CAS Registry Mumber 76502-78-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,0 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 76502-78:
(7*7)+(6*6)+(5*5)+(4*0)+(3*2)+(2*7)+(1*8)=138
138 % 10 = 8
So 76502-78-8 is a valid CAS Registry Number.

Synthesis of 1-Aryl-6,7,8,9-tetrahydrobenzothienothiazolopyrimidin-5(H)-ones

Gakhar, H. K.,Madan, Arun,Kumar, Naresh

, p. 250 - 252 (2007/10/02)

1-Aryl-6,7,8,9-tetrahydrobenzothienothiazolopyrimidin-5(H)-ones (IIa-e) have been synthesised by the condensation of ethyl 2-amino-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate with α-thiocyanoacetophenones.Various intermediates have been isolated and their structures established on the basis of IR and PMR data.The course of reaction has also been rationalized.
