The CAS Registry Mumber 1602-53-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1602-53: (6*1)+(5*6)+(4*0)+(3*2)+(2*5)+(1*3)=55 55 % 10 = 5 So 1602-53-5 is a valid CAS Registry Number.
