Check Digit Verification of cas no

The CAS Registry Mumber 1338699-08-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,6,9 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1338699-08:
(9*1)+(8*3)+(7*3)+(6*8)+(5*6)+(4*9)+(3*9)+(2*0)+(1*8)=203
203 % 10 = 3
So 1338699-08-3 is a valid CAS Registry Number.
