The CAS Registry Mumber 2121-89-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,2 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2121-89:
(6*2)+(5*1)+(4*2)+(3*1)+(2*8)+(1*9)=53
53 % 10 = 3
So 2121-89-3 is a valid CAS Registry Number.
