Check Digit Verification of cas no

The CAS Registry Mumber 1242174-79-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,1,7 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1242174-79:
(9*1)+(8*2)+(7*4)+(6*2)+(5*1)+(4*7)+(3*4)+(2*7)+(1*9)=133
133 % 10 = 3
So 1242174-79-3 is a valid CAS Registry Number.
