Check Digit Verification of cas no

The CAS Registry Mumber 289911-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,9,1 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 289911-81:
(8*2)+(7*8)+(6*9)+(5*9)+(4*1)+(3*1)+(2*8)+(1*1)=195
195 % 10 = 5
So 289911-81-5 is a valid CAS Registry Number.
