Check Digit Verification of cas no

The CAS Registry Mumber 81484-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,8 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81484-33:
(7*8)+(6*1)+(5*4)+(4*8)+(3*4)+(2*3)+(1*3)=135
135 % 10 = 5
So 81484-33-5 is a valid CAS Registry Number.
