The CAS Registry Mumber 2528-18-9 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, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2528-18: (6*2)+(5*5)+(4*2)+(3*8)+(2*1)+(1*8)=79 79 % 10 = 9 So 2528-18-9 is a valid CAS Registry Number.
