The CAS Registry Mumber 875-18-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 5 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 875-18: (5*8)+(4*7)+(3*5)+(2*1)+(1*8)=93 93 % 10 = 3 So 875-18-3 is a valid CAS Registry Number.
