Tris(carbobenzyloxy)-L-arginyl-Nε-(carbobenzyloxy)-L-lysine is a complex peptide compound consisting of three L-arginine and one L-lysine residues. The carbobenzyloxy (Cbz) groups are protecting agents used in peptide synthesis, which protect the amino and carboxyl groups of the amino acids, allowing for selective coupling reactions. In tris(carbobenzyloxy)-L-arginyl-Nε-(carbobenzyloxy)-L-lysine, the L-arginine residues are tris-protected with Cbz groups, while the L-lysine residue has a single Cbz protecting group on its ε-amino group. This specific chemical structure is important for the synthesis of larger peptides and proteins, as it allows for the controlled assembly of amino acids in a stepwise manner. The Cbz groups can be removed under specific conditions to reveal the free amino and carboxyl groups, enabling further peptide bond formation. tris(carbobenzyloxy)-L-arginyl-Nε-(carbobenzyloxy)-L-lysine serves as a building block in the construction of more complex peptide sequences and is a testament to the precision and control required in peptide chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 80622-02-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,2 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80622-02:
(7*8)+(6*0)+(5*6)+(4*2)+(3*2)+(2*0)+(1*2)=102
102 % 10 = 2
So 80622-02-2 is a valid CAS Registry Number.

Immunoactive peptides: VI. Synthesis of new analogs of thymopoietin

Anokhina,Levushkina,Sorochinskaya

, p. 1339 - 1344 (2007/10/03)

A new scheme for preparing a pentapeptide of thymopoietin (ArgLysAspValTyr, TP-5) is proposed, featuring a versatile combination of the maximal and minimal protection principles. The scheme was used to prepare the Gly2, Pro2, Ala3, and Arg2, Ala3 analogs of TP-5.
