Check Digit Verification of cas no

The CAS Registry Mumber 188399-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,3,9 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188399-75:
(8*1)+(7*8)+(6*8)+(5*3)+(4*9)+(3*9)+(2*7)+(1*5)=209
209 % 10 = 9
So 188399-75-9 is a valid CAS Registry Number.
