The CAS Registry Mumber 2116-14-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 6 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2116-14: (6*2)+(5*1)+(4*1)+(3*6)+(2*1)+(1*4)=45 45 % 10 = 5 So 2116-14-5 is a valid CAS Registry Number.
