Z-5-Ava-Gly-OEt, also known as Z-5-Ava-Glycine Ethyl Ester, is a synthetic chemical compound with the molecular formula C14H21N3O5. It is a derivative of the naturally occurring amino acid, L-leucine, and is characterized by the presence of a hydroxyethyl group (-CH2CH2OH) attached to the carboxylic acid group. The compound is named after its structure, where "Z" stands for the benzyloxycarbonyl (Cbz) protecting group, "5-Ava" represents the 5-aminovaleric acid, and "Gly-OEt" indicates the glycine ethyl ester. Z-5-Ava-Gly-OEt is primarily used in peptide synthesis as a building block for the construction of larger peptide sequences, and its protecting groups help prevent unwanted side reactions during the synthesis process.
The CAS Registry Mumber 76523-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,2 and 3 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 76523-74: (7*7)+(6*6)+(5*5)+(4*2)+(3*3)+(2*7)+(1*4)=145 145 % 10 = 5 So 76523-74-5 is a valid CAS Registry Number.
