Check Digit Verification of cas no

The CAS Registry Mumber 2209-26-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2209-26:
(6*2)+(5*2)+(4*0)+(3*9)+(2*2)+(1*6)=59
59 % 10 = 9
So 2209-26-9 is a valid CAS Registry Number.
