Check Digit Verification of cas no

The CAS Registry Mumber 153137-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,1,3 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 153137-85:
(8*1)+(7*5)+(6*3)+(5*1)+(4*3)+(3*7)+(2*8)+(1*5)=120
120 % 10 = 0
So 153137-85-0 is a valid CAS Registry Number.
