Check Digit Verification of cas no

The CAS Registry Mumber 1057216-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,7,2,1 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1057216-55:
(9*1)+(8*0)+(7*5)+(6*7)+(5*2)+(4*1)+(3*6)+(2*5)+(1*5)=133
133 % 10 = 3
So 1057216-55-3 is a valid CAS Registry Number.
