The CAS Registry Mumber 2528-71-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 8 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2528-71: (6*2)+(5*5)+(4*2)+(3*8)+(2*7)+(1*1)=84 84 % 10 = 4 So 2528-71-4 is a valid CAS Registry Number.
