Check Digit Verification of cas no

The CAS Registry Mumber 139517-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,1 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139517-52:
(8*1)+(7*3)+(6*9)+(5*5)+(4*1)+(3*7)+(2*5)+(1*2)=145
145 % 10 = 5
So 139517-52-5 is a valid CAS Registry Number.
