Check Digit Verification of cas no

The CAS Registry Mumber 331283-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,2,8 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 331283-87:
(8*3)+(7*3)+(6*1)+(5*2)+(4*8)+(3*3)+(2*8)+(1*7)=125
125 % 10 = 5
So 331283-87-5 is a valid CAS Registry Number.
