O-Carboxymethyl-tyrosin, also known as O-carboxymethyl-L-tyrosine or O-CM-Tyr, is a synthetic derivative of the amino acid L-tyrosine. It is characterized by the presence of a carboxymethyl group (-CH2COOH) attached to the hydroxyl group of the tyrosine molecule. This modification enhances the solubility and stability of the compound in various environments. O-Carboxymethyl-tyrosin is used in research and development, particularly in the fields of biochemistry and pharmaceuticals, for studying enzyme kinetics, protein structure, and as a building block in the synthesis of more complex molecules. It is also employed as a reagent in the detection and quantification of certain enzymes, such as proteases, due to its ability to mimic the behavior of natural substrates.

Check Digit Verification of cas no

The CAS Registry Mumber 4840-43-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,4 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4840-43:
(6*4)+(5*8)+(4*4)+(3*0)+(2*4)+(1*3)=91
91 % 10 = 1
So 4840-43-1 is a valid CAS Registry Number.
