Beta-1,2-glucan, also known as laminarin, is a type of polysaccharide composed of glucose monomers linked by beta-1,2-glycosidic bonds. It is a major component of the cell walls of many fungi and some algae, and is also found in the cell walls of certain bacteria. Beta-1,2-glucan has various biological activities, including immunomodulatory effects, and is being studied for its potential use in the development of anti-cancer and anti-inflammatory drugs. It is also used as a food additive and a dietary supplement due to its prebiotic properties, which promote the growth of beneficial gut bacteria.
The CAS Registry Mumber 9051-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,5 and 1 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 9051-99: (6*9)+(5*0)+(4*5)+(3*1)+(2*9)+(1*9)=104 104 % 10 = 4 So 9051-99-4 is a valid CAS Registry Number.
