"Z-Lys(Mtr)-Lys(Mtr)-Leu-Leu-NH2" is a synthetic peptide consisting of five amino acids: two lysines with Mtr (methionyl) modifications, two leucines, and one unmodified lysine. The peptide is characterized by the presence of the Z group, which is a protecting group used in peptide synthesis to prevent unwanted side reactions. The Mtr modifications on the lysine residues are likely intended to provide specific properties or functions to the peptide, such as increased hydrophobicity or stability. This sequence could be used in various applications, including drug development, as a component of a larger protein, or for studying protein-protein interactions. The peptide's structure and modifications make it a complex molecule with potential biological significance, depending on its intended use.

Check Digit Verification of cas no

The CAS Registry Mumber 84552-26-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,5 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84552-26:
(7*8)+(6*4)+(5*5)+(4*5)+(3*2)+(2*2)+(1*6)=141
141 % 10 = 1
So 84552-26-1 is a valid CAS Registry Number.

4-Methoxy-2,3,6-trimethylbenzenesulfonyl (Mtr): a New Amino and Imidazole Protecting Group in Peptide Synthesis

Wakimasu, Mitsuhiro,Kitada, Chieko,Fujino, Masahiko

, p. 2766 - 2779 (2007/10/02)

The 4-methoxy-2,3,6-trimethylbenzenesulfonyl (Mtr) group was introduced as a protecting group for the amino function, especially the ε-amino function of lysine, and the imidazole ring of histidine.The Nε-Mtr group was removable by dilute methanesulfonic acid-containing trifluoroacetic acid-thioanisole, but was stable to trifluoroacetic acid or catalytic hydrogenation.The Nim-Mtr group was removable by trifluoroacetic acid-dimethylsulfide or 1-hydroxybenzotriazole, but was more stable than the Nim-Tos or the Nim-Mbs group with triethylamine.To examine the usefulness of the Mtr group as a protecting group for use in peptide synthesis, mastoparan X and chicken gastrin releasing peptide (c-GRP) were synthesized, and this group was found to be very convenient for general solution synthesis.In particular, the introduction of Lys(Mtr) made possible a new strategy in peptide synthesis.Keywords-4-methoxy-2,3,6-trimethylbenzenesulfonyl (Mtr); Nε-4-methoxy-2,3,6-trimethylbenzenesulfonyllysine; Nim-4-methoxy-2,3,6-trimethylbenzenesulfonylhistidine; methanesulfonic acid-trifluoroacetic acid-thioanisole deprotection; trifluoroacetic acid-dimethylsulfide deprotection; mastoparan X; chicken gastrin releasing peptide
