Check Digit Verification of cas no

The CAS Registry Mumber 199599-65-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,5,9 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 199599-65:
(8*1)+(7*9)+(6*9)+(5*5)+(4*9)+(3*9)+(2*6)+(1*5)=230
230 % 10 = 0
So 199599-65-0 is a valid CAS Registry Number.
