The chemical sequence "Z-Thr-Lys(Mtr)-Ile-Tyr-Pro-Arg(Pme)-Gly-OBut" represents a peptide, which is a short chain of amino acids. In this specific peptide, the amino acids are linked together in the following order: Z-protected threonine (Z-Thr), lysine with a methionine side chain (Lys(Mtr)), isoleucine (Ile), tyrosine (Tyr), proline (Pro), arginine with a palmitoyl group (Arg(Pme)), and glycine (Gly). The "OBut" at the end indicates that the peptide is capped with a tert-butyloxycarbonyl (Boc) protecting group, which is commonly used in peptide synthesis to protect the amino group of the terminal amino acid. This peptide sequence is likely to be a part of a larger bioactive molecule or a component in a pharmaceutical or research context, where the specific arrangement and modifications of amino acids can influence its biological activity or stability.

Check Digit Verification of cas no

The CAS Registry Mumber 84552-70-5 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, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84552-70:
(7*8)+(6*4)+(5*5)+(4*5)+(3*2)+(2*7)+(1*0)=145
145 % 10 = 5
So 84552-70-5 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
