Check Digit Verification of cas no
The CAS Registry Mumber 74695-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,9 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74695-25:
(7*7)+(6*4)+(5*6)+(4*9)+(3*5)+(2*2)+(1*5)=163
163 % 10 = 3
So 74695-25-3 is a valid CAS Registry Number.

Thienopyridines. Part 2. Application of the Conrad-Limpach and Gould-Jacobs Reactions to the Synthesis of Thienopyridin-4(1H)-ones.

Thermal cyclisation of the enamine (1), derived from 3-amino-2-methoxycarbonylthiophen and dimethyl acetylenedicarboxylate, led to 2,7-bis-methoxycarbonylthienopyridin-4(1H)-one (2).The related adducts (10a and 10b) gave the thienopyridin-4(1H)-ones (11a and 11b).Some reactions of the new thienopyridine derivatives have been investigated.
