Check Digit Verification of cas no

The CAS Registry Mumber 313948-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,9,4 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 313948-67:
(8*3)+(7*1)+(6*3)+(5*9)+(4*4)+(3*8)+(2*6)+(1*7)=153
153 % 10 = 3
So 313948-67-3 is a valid CAS Registry Number.

α-Oxoketene dithioacetals mediated benzoannelation of aromatic heterocycles: An efficient regiocontrolled synthesis of highly substituted and polycyclic benzo[b]thiophenes

Suresh,Barun, Okram,Ila,Junjappa

, p. 8153 - 8160 (2000)

An efficient regiocontrolled synthesis of highly substituted and complex polycyclic benzo[b]thiophenes has been developed via our benzoannelation strategy involving conjugate addition-displacement on a variety of α-oxoketene dithioacetals by carbanions derived from 2- and 3-cyanomethylthiophenes followed by acid induced cyclization of the resulting conjugate adducts.
