Check Digit Verification of cas no

The CAS Registry Mumber 5209-53-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5209-53:
(6*5)+(5*2)+(4*0)+(3*9)+(2*5)+(1*3)=80
80 % 10 = 0
So 5209-53-0 is a valid CAS Registry Number.
