Check Digit Verification of cas no

The CAS Registry Mumber 500220-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,2,2 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 500220-31:
(8*5)+(7*0)+(6*0)+(5*2)+(4*2)+(3*0)+(2*3)+(1*1)=65
65 % 10 = 5
So 500220-31-5 is a valid CAS Registry Number.
