Check Digit Verification of cas no

The CAS Registry Mumber 24209-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,2,0 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 24209-38:
(7*2)+(6*4)+(5*2)+(4*0)+(3*9)+(2*3)+(1*8)=89
89 % 10 = 9
So 24209-38-9 is a valid CAS Registry Number.
