Check Digit Verification of cas no

The CAS Registry Mumber 502-29-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 502-29:
(5*5)+(4*0)+(3*2)+(2*2)+(1*9)=44
44 % 10 = 4
So 502-29-4 is a valid CAS Registry Number.
