Check Digit Verification of cas no

The CAS Registry Mumber 138639-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,3 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138639-29:
(8*1)+(7*3)+(6*8)+(5*6)+(4*3)+(3*9)+(2*2)+(1*9)=159
159 % 10 = 9
So 138639-29-9 is a valid CAS Registry Number.
