Check Digit Verification of cas no

The CAS Registry Mumber 137451-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,5 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137451-84:
(8*1)+(7*3)+(6*7)+(5*4)+(4*5)+(3*1)+(2*8)+(1*4)=134
134 % 10 = 4
So 137451-84-4 is a valid CAS Registry Number.

A Convenient Synthesis of Ethyl 2-(4-Nitrophenyl)-3,4-disubstituted and c-Fused Thiophene-5-carboxylates

Rangnekar, D. W.,Mavlankar, S. V.

, p. 1455 - 1457 (2007/10/02)

A convenient one step synthesis of the hitherto unknown ethyl 2-(4-nitrophenyl-3,4-disubstituted and c-fused thiophene-5-carboxylates was achieved by the condensation of ethyl 4-nitrobenzylthioacetate with a variety of 1,2-dicarbonyl compounds using sodiu
