The CAS Registry Mumber 5284-11-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 4 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5284-11: (6*5)+(5*2)+(4*8)+(3*4)+(2*1)+(1*1)=87 87 % 10 = 7 So 5284-11-7 is a valid CAS Registry Number.
