Galactoxylan is a complex polysaccharide found in the cell walls of plants, particularly in the secondary cell walls of certain grasses and cereals. It is composed of a xylan backbone, which is a linear chain of xylose (a sugar) units, to which galactose (another sugar) side chains are attached. This structure gives galactoxylan its unique properties, such as its ability to form gels and its role in plant cell wall rigidity. Galactoxylan is also of interest in the food and pharmaceutical industries due to its potential health benefits, such as prebiotic effects that promote the growth of beneficial gut bacteria.
The CAS Registry Mumber 9009-71-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 9 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 9009-71: (6*9)+(5*0)+(4*0)+(3*9)+(2*7)+(1*1)=96 96 % 10 = 6 So 9009-71-6 is a valid CAS Registry Number.
