The CAS Registry Mumber 1530-18-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,3 and 0 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1530-18: (6*1)+(5*5)+(4*3)+(3*0)+(2*1)+(1*8)=53 53 % 10 = 3 So 1530-18-3 is a valid CAS Registry Number.
