"Z-N-Methyl-L-valyl-D-α-oxy-isovaleryl-L-valeryl-D-α-oxy-isovaleryl-D-α-oxy-isovaleriansaeure-tert.-butylester" is a complex peptide derivative with a unique structure. It is composed of a series of amino acid residues, including L-valine, D-α-oxy-isovaleric acid, and D-α-oxy-isovaleryl-D-α-oxy-isovaleric acid, which are linked together in a specific sequence. The "Z" prefix indicates the presence of a benzyloxycarbonyl (Z) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. The "N-methyl" group suggests that one of the amino groups in the peptide has been methylated, which can affect the peptide's properties and reactivity. The "t-butylester" at the end of the molecule indicates the presence of a tert-butyl ester group, which can be used to protect the carboxylic acid functionality during synthesis. Z-N-Methyl-L-valyl-D-α-oxy-isovaleryl-L-valeryl-D-α-oxy-isovaleryl-D-α-oxy-isovaleriansaeure-tert.-butylester is likely to be used in advanced peptide chemistry or as a building block for more complex molecules, given its intricate structure and protective groups.
The CAS Registry Mumber 2619-69-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,1 and 9 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2619-69: (6*2)+(5*6)+(4*1)+(3*9)+(2*6)+(1*9)=94 94 % 10 = 4 So 2619-69-4 is a valid CAS Registry Number.
