163158-19-8 Usage
General Description
The chemical "H-MET-GLU-VAL-GLY-TRP-TYR-ARG-PRO-PRO-PHE-SER-ARG-VAL-VAL-HIS-LEU-TYR-ARG-ASN-GLY-LYS-OH" is a peptide composed of 21 amino acids, with the sequence starting with methionine (MET) and ending with lysine (LYS) and hydroxyl (OH) group. The peptide contains a variety of amino acids, including hydrophobic (TYR, TRP, LEU, VAL), polar (SER, GLU, HIS, ASN), and positively charged (ARG, LYS) residues. The presence of these amino acids suggests that the peptide may have a potential role in functions such as cell signaling, enzyme regulation, or protein-protein interactions. The hydroxyl group indicates that the peptide is likely a C-terminal amidated peptide, which may confer stability and resistance to degradation in biological systems.
Check Digit Verification of cas no
The CAS Registry Mumber 163158-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,1,5 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 163158-19:
(8*1)+(7*6)+(6*3)+(5*1)+(4*5)+(3*8)+(2*1)+(1*9)=128
128 % 10 = 8
So 163158-19-8 is a valid CAS Registry Number.
