Check Digit Verification of cas no

The CAS Registry Mumber 166271-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,2,7 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 166271-30:
(8*1)+(7*6)+(6*6)+(5*2)+(4*7)+(3*1)+(2*3)+(1*0)=133
133 % 10 = 3
So 166271-30-3 is a valid CAS Registry Number.
