Check Digit Verification of cas no

The CAS Registry Mumber 1131-31-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1131-31:
(6*1)+(5*1)+(4*3)+(3*1)+(2*3)+(1*1)=33
33 % 10 = 3
So 1131-31-3 is a valid CAS Registry Number.
