Alpha-D-Mannan, also known as (1→3)-α-D-Mannan, is a polysaccharide composed of α-D-mannose units linked by (1→3) glycosidic bonds. It is a linear, unbranched polymer that is found in various plants, particularly in the cell walls of some fungi and algae. This type of mannan is known for its unique biological properties, such as its ability to interact with the immune system and its potential use in pharmaceutical applications, including as an antitumor agent. The structure of α-D-Mannan contributes to its solubility and viscosity in aqueous solutions, making it a subject of interest in both scientific research and industrial applications.
The CAS Registry Mumber 9052-03-3 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 2 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 9052-03: (6*9)+(5*0)+(4*5)+(3*2)+(2*0)+(1*3)=83 83 % 10 = 3 So 9052-03-3 is a valid CAS Registry Number.
