Check Digit Verification of cas no

The CAS Registry Mumber 139130-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,3 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139130-97:
(8*1)+(7*3)+(6*9)+(5*1)+(4*3)+(3*0)+(2*9)+(1*7)=125
125 % 10 = 5
So 139130-97-5 is a valid CAS Registry Number.
