"N-{N-[N-(N-benzyloxycarbonyl-glycyl)-L-leucyl]-glycyl}-L-leucine methyl ester" is a complex peptide compound consisting of a series of amino acids linked together. The structure begins with a glycine (Gly) residue that is N-protected with a benzyloxycarbonyl (Z) group, which is a common protecting group in peptide synthesis to prevent unwanted side reactions. This is followed by a leucine (Leu) residue, and then another glycine (Gly) residue. The peptide chain is extended with another leucine (Leu) residue, and finally, a glycine (Gly) residue is attached, which is then methyl esterified. N-{N-[N-(N-benzyloxycarbonyl-glycyl)-L-leucyl]-glycyl}-L-leucine methyl ester is a synthetic peptide that could be used in various applications, such as in the development of drugs, as a research tool in biochemistry, or in the study of protein structure and function. The specific sequence and protection groups suggest that it is designed for controlled synthesis and potential biological activity, although without additional context, the exact purpose or application is not specified.
The CAS Registry Mumber 5497-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,9 and 7 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5497-72: (6*5)+(5*4)+(4*9)+(3*7)+(2*7)+(1*2)=123 123 % 10 = 3 So 5497-72-3 is a valid CAS Registry Number.
