The CAS Registry Mumber 457-21-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 7 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 457-21: (5*4)+(4*5)+(3*7)+(2*2)+(1*1)=66 66 % 10 = 6 So 457-21-6 is a valid CAS Registry Number.
