The chemical compound "α-Z-Nε-BOC-L-Lysyl>-L-α-amino-buttersaeure-methylester" is a complex peptide derivative. It features a lysine residue, which is an essential amino acid, with a butyric acid chain attached to its α-amino group. The Nα position of the lysine is protected by a benzyloxycarbonyl (Z) group, which is a common protecting group in peptide synthesis to prevent unwanted side reactions. The Nε position, another amino group on the lysine, is also protected, this time by a tert-butoxycarbonyl (BOC) group. The compound is further characterized by a methyl ester group at the end of the butyric acid chain, which can be used to control the reactivity of the carboxyl group during peptide synthesis. α-Z-Nε-BOC-L-Lysyl>-L-α-amino-buttersaeure-methylester is likely used in the synthesis of larger peptides or proteins, where the protecting groups are strategically removed at the appropriate stages to allow for the formation of peptide bonds.
The CAS Registry Mumber 7652-88-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,5 and 2 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7652-88: (6*7)+(5*6)+(4*5)+(3*2)+(2*8)+(1*8)=122 122 % 10 = 2 So 7652-88-2 is a valid CAS Registry Number.
