Check Digit Verification of cas no

The CAS Registry Mumber 1227161-76-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,1,6 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1227161-76:
(9*1)+(8*2)+(7*2)+(6*7)+(5*1)+(4*6)+(3*1)+(2*7)+(1*6)=133
133 % 10 = 3
So 1227161-76-3 is a valid CAS Registry Number.
