α-Neuraminic acid, also known as Neu5Ac or vitamin B5, is a naturally occurring organic compound and a key component of various glycoconjugates, including glycoproteins and glycolipids. It is a nine-carbon monosaccharide with a carboxylic acid group and a hydroxyl group, featuring a pyruvate acetal modification. α-Neuraminic acid plays a crucial role in numerous biological processes, such as cell signaling, immune response, and pathogen recognition. It is particularly important for the proper functioning of the nervous system and is involved in the synthesis of sialic acids, which are essential for the stability and structure of cell membranes. The compound can be found in various foods, including meat, eggs, and dairy products, and is also produced industrially through chemical synthesis or biotechnological methods.
The CAS Registry Mumber 41546-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,5,4 and 6 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 41546-22: (7*4)+(6*1)+(5*5)+(4*4)+(3*6)+(2*2)+(1*2)=99 99 % 10 = 9 So 41546-22-9 is a valid CAS Registry Number.
