Check Digit Verification of cas no

The CAS Registry Mumber 42457-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,5 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 42457-24:
(7*4)+(6*2)+(5*4)+(4*5)+(3*7)+(2*2)+(1*4)=109
109 % 10 = 9
So 42457-24-9 is a valid CAS Registry Number.
