Check Digit Verification of cas no

The CAS Registry Mumber 103678-18-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,7 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103678-18:
(8*1)+(7*0)+(6*3)+(5*6)+(4*7)+(3*8)+(2*1)+(1*8)=118
118 % 10 = 8
So 103678-18-8 is a valid CAS Registry Number.
