"Z-Arg(NO2)-5-Ava-Gly-OEt" is a synthetic peptide compound consisting of five amino acids: Z-Arg(NO2), 5-Ava, Gly, and OEt. The "Z" group is a protecting group used in peptide synthesis to prevent unwanted side reactions. The "Arg(NO2)" represents an arginine amino acid with a nitro group substitution, while "5-Ava" is a non-natural amino acid, 5-aminovaleric acid. "Gly" stands for glycine, the simplest amino acid, and "OEt" indicates an ethyl ester group attached to the carboxylic acid end of the peptide. This specific sequence and structure of amino acids give the compound unique properties and potential applications in various fields, such as pharmaceuticals, research, and chemical synthesis.
The CAS Registry Mumber 76523-76-7 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 6 respectively. Calculate Digit Verification of CAS Registry Number 76523-76: (7*7)+(6*6)+(5*5)+(4*2)+(3*3)+(2*7)+(1*6)=147 147 % 10 = 7 So 76523-76-7 is a valid CAS Registry Number.
