The CAS Registry Mumber 1128-15-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 8 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1128-15: (6*1)+(5*1)+(4*2)+(3*8)+(2*1)+(1*5)=50 50 % 10 = 0 So 1128-15-0 is a valid CAS Registry Number.
