Check Digit Verification of cas no

The CAS Registry Mumber 33732-91-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,3 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33732-91:
(7*3)+(6*3)+(5*7)+(4*3)+(3*2)+(2*9)+(1*1)=111
111 % 10 = 1
So 33732-91-1 is a valid CAS Registry Number.
