Check Digit Verification of cas no

The CAS Registry Mumber 161772-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,7,7 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161772-32:
(8*1)+(7*6)+(6*1)+(5*7)+(4*7)+(3*2)+(2*3)+(1*2)=133
133 % 10 = 3
So 161772-32-3 is a valid CAS Registry Number.
