Check Digit Verification of cas no

The CAS Registry Mumber 1156038-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,6,0,3 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1156038-75:
(9*1)+(8*1)+(7*5)+(6*6)+(5*0)+(4*3)+(3*8)+(2*7)+(1*5)=143
143 % 10 = 3
So 1156038-75-3 is a valid CAS Registry Number.

A convenient synthesis of isothiochromen-4-one 2,2-dioxide was carried out via cyclisation of o-cyanobenzyl thioacetate by a Thorpe reaction. The reactions of isothiochromen-4-one 2,2-dioxide with nitrogen-containing nucleophilic reagents have been investigated.
