The CAS Registry Mumber 502-09-0 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, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 502-09: (5*5)+(4*0)+(3*2)+(2*0)+(1*9)=40 40 % 10 = 0 So 502-09-0 is a valid CAS Registry Number.
