Check Digit Verification of cas no

The CAS Registry Mumber 138666-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,6 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138666-59:
(8*1)+(7*3)+(6*8)+(5*6)+(4*6)+(3*6)+(2*5)+(1*9)=168
168 % 10 = 8
So 138666-59-8 is a valid CAS Registry Number.
