The CAS Registry Mumber 22121-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,2 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 22121-27:

53 % 10 = 3
So 22121-27-3 is a valid CAS Registry Number.
