123562-20-9 Usage
General Description
The chemical sequence "H-CYS-SER-CYS-SER-SER-TRP-LEU-ASP-LYS-GLU-CYS-VAL-TYR-PHE-CYS-HIS-LEU-ASP-ILE-ILE-TRP-OH" is a peptide consisting of 21 amino acids. It begins with a histidine (H) followed by a series of cysteine (CYS), serine (SER), tryptophan (TRP), leucine (LEU), aspartic acid (ASP), lysine (LYS), glutamic acid (GLU), valine (VAL), tyrosine (TYR), phenylalanine (PHE), and histidine (HIS). The sequence ends with two isoleucine (ILE) and a tryptophan (TRP) at the C-terminus, with a hydroxyl group (OH) attached to the terminal tryptophan. Peptides like this can have a variety of biological functions, including hormone regulation, enzyme activity, and cell signaling.
Check Digit Verification of cas no
The CAS Registry Mumber 123562-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,6 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123562-20:
(8*1)+(7*2)+(6*3)+(5*5)+(4*6)+(3*2)+(2*2)+(1*0)=99
99 % 10 = 9
So 123562-20-9 is a valid CAS Registry Number.
