Check Digit Verification of cas no

The CAS Registry Mumber 138331-58-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,3 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138331-58:
(8*1)+(7*3)+(6*8)+(5*3)+(4*3)+(3*1)+(2*5)+(1*8)=125
125 % 10 = 5
So 138331-58-5 is a valid CAS Registry Number.
