Check Digit Verification of cas no

The CAS Registry Mumber 117516-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,1 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117516-89:
(8*1)+(7*1)+(6*7)+(5*5)+(4*1)+(3*6)+(2*8)+(1*9)=129
129 % 10 = 9
So 117516-89-9 is a valid CAS Registry Number.

One-step synthesis of 2-aminothieno [2,3-d]thiazen-4-ones in some cases 5,6-anellated from ethyl 2-benzoylthioureidothiophen-3-carboxylates and evaluation of their anti-allergy activity

Leistner,Guetschow,Wagner,Grupe,Boehme

, p. 466 - 470 (2007/10/02)

The cyclization of ethyl 2-benzoylthioureidothiophen-3-carboxylates under basic conditions is known to give 2-thioxothieno[2,3-d]pyrimidin-4(1H, 3H)-ones. On the other hand, we have found that ethyl 2-benzoylthioureidothiophen-3-carboxylates 10-16 on trea
