Check Digit Verification of cas no

The CAS Registry Mumber 689260-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,9,2,6 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 689260-65:
(8*6)+(7*8)+(6*9)+(5*2)+(4*6)+(3*0)+(2*6)+(1*5)=209
209 % 10 = 9
So 689260-65-9 is a valid CAS Registry Number.
