Check Digit Verification of cas no

The CAS Registry Mumber 56152-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,1,5 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 56152-85:
(7*5)+(6*6)+(5*1)+(4*5)+(3*2)+(2*8)+(1*5)=123
123 % 10 = 3
So 56152-85-3 is a valid CAS Registry Number.
