Check Digit Verification of cas no

The CAS Registry Mumber 724477-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,4,4,7 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 724477-56:
(8*7)+(7*2)+(6*4)+(5*4)+(4*7)+(3*7)+(2*5)+(1*6)=179
179 % 10 = 9
So 724477-56-9 is a valid CAS Registry Number.
