Check Digit Verification of cas no

The CAS Registry Mumber 196597-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,5,9 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 196597-76:
(8*1)+(7*9)+(6*6)+(5*5)+(4*9)+(3*7)+(2*7)+(1*6)=209
209 % 10 = 9
So 196597-76-9 is a valid CAS Registry Number.
