Check Digit Verification of cas no

The CAS Registry Mumber 74583-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,8 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74583-87:
(7*7)+(6*4)+(5*5)+(4*8)+(3*3)+(2*8)+(1*7)=162
162 % 10 = 2
So 74583-87-2 is a valid CAS Registry Number.
