Check Digit Verification of cas no

The CAS Registry Mumber 89817-92-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,1 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89817-92:
(7*8)+(6*9)+(5*8)+(4*1)+(3*7)+(2*9)+(1*2)=195
195 % 10 = 5
So 89817-92-5 is a valid CAS Registry Number.
