6745-19-3 Usage
General Description
H-ALA-ALA-D-ALA-OH, also known as H-Tri-ala-OH, is a tripeptide composed of two alanine residues (ALA) in the L-configuration, and one alanine residue (ALA) in the D-configuration. This chemical composition denotes the orientation of the amino acids, which is essential in determining the molecule's structure and function. It has a molecular weight of 259.28 g/mol. It plays a significant role in biological research, particularly in the study of peptide synthesis, protein structure, and function, as well as in medicine and pharmaceuticals, given its importance in antimicrobial resistance. It serves as a precursor in the biosynthesis of peptidoglycan, a crucial component of bacterial cell walls. Therefore, it corresponds to a frequent target for antibiotics.
Check Digit Verification of cas no
The CAS Registry Mumber 6745-19-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6745-19:
(6*6)+(5*7)+(4*4)+(3*5)+(2*1)+(1*9)=113
113 % 10 = 3
So 6745-19-3 is a valid CAS Registry Number.
