Check Digit Verification of cas no

The CAS Registry Mumber 138990-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,9 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138990-71:
(8*1)+(7*3)+(6*8)+(5*9)+(4*9)+(3*0)+(2*7)+(1*1)=173
173 % 10 = 3
So 138990-71-3 is a valid CAS Registry Number.
