"Nα-Adamantyloxycarbonyl-Nε-benzyloxycarbonyl-L-lysin" is a complex peptide derivative that serves as a protecting group in peptide synthesis. It is composed of an L-lysine molecule, which is an essential amino acid, with two protecting groups attached to it. The Nα position is protected by an adamantyloxycarbonyl (Adoc) group, which is a bulky, hydrophobic protecting group that helps prevent unwanted side reactions during peptide synthesis. The Nε position is protected by a benzyloxycarbonyl (Z) group, which is a commonly used protecting group that can be easily removed under mild acidic conditions. This specific combination of protecting groups allows for the controlled synthesis of peptides, ensuring that the L-lysine residue is selectively protected and can be incorporated into the growing peptide chain in a controlled manner. The use of such protecting groups is crucial in the field of peptide chemistry, as it enables the synthesis of complex peptide sequences with high precision and selectivity.
The CAS Registry Mumber 5854-71-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 4 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5854-71: (6*5)+(5*8)+(4*5)+(3*4)+(2*7)+(1*1)=117 117 % 10 = 7 So 5854-71-7 is a valid CAS Registry Number.
