4-Oxalysine, also known as 4-oxo-L-lysine or L-4-oxalysine, is a non-proteinogenic amino acid derived from the oxidation of lysine, an essential amino acid found in proteins. It is characterized by the presence of a carbonyl group (C=O) at the 4-position of the lysine side chain, which imparts unique chemical properties and reactivity. 4-Oxalysine plays a significant role in various biological processes, including protein folding, stability, and function, as well as in the formation of advanced glycation end products (AGEs) in the Maillard reaction, which is involved in the development of chronic diseases such as diabetes and neurodegenerative disorders. The presence of 4-oxalysine in proteins can also serve as a biomarker for oxidative stress and protein damage.

Check Digit Verification of cas no

The CAS Registry Mumber 997-44-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 997-44:
(5*9)+(4*9)+(3*7)+(2*4)+(1*4)=114
114 % 10 = 4
So 997-44-4 is a valid CAS Registry Number.
