The CAS Registry Mumber 2321-86-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,2 and 1 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2321-86: (6*2)+(5*3)+(4*2)+(3*1)+(2*8)+(1*6)=60 60 % 10 = 0 So 2321-86-0 is a valid CAS Registry Number.
