The CAS Registry Mumber 2631-16-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 1 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2631-16: (6*2)+(5*6)+(4*3)+(3*1)+(2*1)+(1*6)=65 65 % 10 = 5 So 2631-16-5 is a valid CAS Registry Number.
