Check Digit Verification of cas no

The CAS Registry Mumber 139012-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,1 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139012-63:
(8*1)+(7*3)+(6*9)+(5*0)+(4*1)+(3*2)+(2*6)+(1*3)=108
108 % 10 = 8
So 139012-63-8 is a valid CAS Registry Number.
