The CAS Registry Mumber 33281-24-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,8 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33281-24:
(7*3)+(6*3)+(5*2)+(4*8)+(3*1)+(2*2)+(1*4)=92
92 % 10 = 2
So 33281-24-2 is a valid CAS Registry Number.
