The CAS Registry Mumber 516-31-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 6 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 516-31: (5*5)+(4*1)+(3*6)+(2*3)+(1*1)=54 54 % 10 = 4 So 516-31-4 is a valid CAS Registry Number.
