16874-81-0 Usage
General Description
H-HIS-PHE-OH is a tripeptide molecule consisting of three amino acids: histidine, phenylalanine, and an N-terminal hydrogen. Histidine is an essential amino acid involved in various physiological processes, including immune response, digestion, and tissue repair. Phenylalanine is another essential amino acid that serves as a building block for proteins and is involved in the production of neurotransmitters. When combined in the tripeptide form, H-HIS-PHE-OH may have potential applications in drug development, nutritional supplements, and research for understanding the role of these amino acids in various biological processes.
Check Digit Verification of cas no
The CAS Registry Mumber 16874-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,7 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16874-81:
(7*1)+(6*6)+(5*8)+(4*7)+(3*4)+(2*8)+(1*1)=140
140 % 10 = 0
So 16874-81-0 is a valid CAS Registry Number.

Amino-acids and Peptides. Part 45. The Protection of the Thiol Function of Cysteine and the Imidazole-N of Histidine by the Diphenyl-4-pyridylmethyl Group
Coyle, Susan,Hallett, Allan,Munns, Michael S.,Young, Geoffrey T.
, p. 522 - 528 (2007/10/02)
S-(Diphenyl-4-pyridylmethyl)-L-cysteine (1) and its derivatives (2)-(7) have been prepared and used in peptide synthesis.In contrast to the analogous S-trityl group, this protection is stable in acid but it is cleaved readily by zinc-acetic acid, by mercury(II) acetate, by iodine, and by electrolytic reduction.N(Im)-Diphenyl-4-pyridylmethyl-L-histidine derivatives (9)-(13) are also reported; the protecting group is again stable to acid but cleaved by hydrogenolysis, by zinc-acetic acid, and by electrolytic reduction, and it has been used in the synthesis of L-histidyl-L-leucine, -L-phenylalanine, and -glycine.
