The CAS Registry Mumber 5020-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,2 and 0 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5020-65: (6*5)+(5*0)+(4*2)+(3*0)+(2*6)+(1*5)=55 55 % 10 = 5 So 5020-65-5 is a valid CAS Registry Number.
