Check Digit Verification of cas no

The CAS Registry Mumber 137003-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,0 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137003-87:
(8*1)+(7*3)+(6*7)+(5*0)+(4*0)+(3*3)+(2*8)+(1*7)=103
103 % 10 = 3
So 137003-87-3 is a valid CAS Registry Number.
