Check Digit Verification of cas no

The CAS Registry Mumber 74984-87-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,8 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74984-87:
(7*7)+(6*4)+(5*9)+(4*8)+(3*4)+(2*8)+(1*7)=185
185 % 10 = 5
So 74984-87-5 is a valid CAS Registry Number.
