Check Digit Verification of cas no

The CAS Registry Mumber 5724-44-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,2 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5724-44:
(6*5)+(5*7)+(4*2)+(3*4)+(2*4)+(1*4)=97
97 % 10 = 7
So 5724-44-7 is a valid CAS Registry Number.
