Check Digit Verification of cas no

The CAS Registry Mumber 138999-82-3 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 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138999-82:
(8*1)+(7*3)+(6*8)+(5*9)+(4*9)+(3*9)+(2*8)+(1*2)=203
203 % 10 = 3
So 138999-82-3 is a valid CAS Registry Number.
