Check Digit Verification of cas no

The CAS Registry Mumber 928613-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,6,1 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 928613-66:
(8*9)+(7*2)+(6*8)+(5*6)+(4*1)+(3*3)+(2*6)+(1*6)=195
195 % 10 = 5
So 928613-66-5 is a valid CAS Registry Number.
