Check Digit Verification of cas no

The CAS Registry Mumber 104196-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,1,9 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104196-99:
(8*1)+(7*0)+(6*4)+(5*1)+(4*9)+(3*6)+(2*9)+(1*9)=118
118 % 10 = 8
So 104196-99-8 is a valid CAS Registry Number.
