Check Digit Verification of cas no

The CAS Registry Mumber 18503-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,0 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18503-87:
(7*1)+(6*8)+(5*5)+(4*0)+(3*3)+(2*8)+(1*7)=112
112 % 10 = 2
So 18503-87-2 is a valid CAS Registry Number.
