Check Digit Verification of cas no

The CAS Registry Mumber 55503-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55503-20:
(7*5)+(6*5)+(5*5)+(4*0)+(3*3)+(2*2)+(1*0)=103
103 % 10 = 3
So 55503-20-3 is a valid CAS Registry Number.
