The CAS Registry Mumber 81474-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,7 and 4 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 81474-53: (7*8)+(6*1)+(5*4)+(4*7)+(3*4)+(2*5)+(1*3)=135 135 % 10 = 5 So 81474-53-5 is a valid CAS Registry Number.
