Gly-Gly-Gly-Gly-OEt, also known as Tetraglycine ethyl ester, is a synthetic peptide consisting of four glycine amino acid residues connected by peptide bonds, with an ethyl ester group attached to the carboxylic acid end. Gly-Gly-Gly-Gly-OEt is a model for understanding peptide conformation and serves as a building block for more complex peptide structures. It is often used in research to study the properties of peptides, such as their solubility, stability, and interactions with other molecules. The simplicity of its structure makes it a useful tool for investigating the fundamental principles governing peptide behavior, which can have implications in various fields, including drug design and biochemistry.
The CAS Registry Mumber 2437-59-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,3 and 7 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2437-59: (6*2)+(5*4)+(4*3)+(3*7)+(2*5)+(1*9)=84 84 % 10 = 4 So 2437-59-4 is a valid CAS Registry Number.
