19361-51-4 Usage
General Description
The chemical "PYR-GLY-PRO-TRP-LEU-GLU-GLU-GLU-GLU-GLU-ALA-TYR(SO3H)-GLY-TRP-MET-ASP-PHE-NH2" is a peptide consisting of 18 amino acids. It begins with pyroglutamic acid (PYR) and glycine (GLY), followed by proline (PRO), tryptophan (TRP), leucine (LEU), and five consecutive glutamic acids (GLU). It then contains alanine (ALA), a tyrosine residue with a sulfonate group (TYR(SO3H)), glycine (GLY), tryptophan (TRP), methionine (MET), aspartic acid (ASP), phenylalanine (PHE), and ends with an amide group (NH2). This chemical sequence represents a specific arrangement of amino acids that can have important biological functions depending on its structural and chemical properties.
Check Digit Verification of cas no
The CAS Registry Mumber 19361-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,6 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19361-51:
(7*1)+(6*9)+(5*3)+(4*6)+(3*1)+(2*5)+(1*1)=114
114 % 10 = 4
So 19361-51-4 is a valid CAS Registry Number.
