Check Digit Verification of cas no

The CAS Registry Mumber 1532557-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,2,5,5 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1532557-33:
(9*1)+(8*5)+(7*3)+(6*2)+(5*5)+(4*5)+(3*7)+(2*3)+(1*3)=157
157 % 10 = 7
So 1532557-33-7 is a valid CAS Registry Number.
