Check Digit Verification of cas no

The CAS Registry Mumber 139102-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,0 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139102-59:
(8*1)+(7*3)+(6*9)+(5*1)+(4*0)+(3*2)+(2*5)+(1*9)=113
113 % 10 = 3
So 139102-59-3 is a valid CAS Registry Number.
