Check Digit Verification of cas no

The CAS Registry Mumber 119616-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,6,1 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119616-49:
(8*1)+(7*1)+(6*9)+(5*6)+(4*1)+(3*6)+(2*4)+(1*9)=138
138 % 10 = 8
So 119616-49-8 is a valid CAS Registry Number.
