The CAS Registry Mumber 20502-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,0 and 2 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 20502-08: (7*2)+(6*0)+(5*5)+(4*0)+(3*2)+(2*0)+(1*8)=53 53 % 10 = 3 So 20502-08-3 is a valid CAS Registry Number.
