Check Digit Verification of cas no

The CAS Registry Mumber 139172-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,7 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139172-23:
(8*1)+(7*3)+(6*9)+(5*1)+(4*7)+(3*2)+(2*2)+(1*3)=129
129 % 10 = 9
So 139172-23-9 is a valid CAS Registry Number.
