Check Digit Verification of cas no

The CAS Registry Mumber 138701-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,0 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138701-58:
(8*1)+(7*3)+(6*8)+(5*7)+(4*0)+(3*1)+(2*5)+(1*8)=133
133 % 10 = 3
So 138701-58-3 is a valid CAS Registry Number.
