Cyanoethyl starch is a modified starch derivative that is prepared by reacting starch with cyanoethyl chloride, resulting in the introduction of cyanoethyl groups onto the starch molecules. This modification enhances the solubility and stability of the starch in various solvents, particularly in organic solvents, and improves its compatibility with other polymers. It is widely used in the pharmaceutical, paper, and textile industries for applications such as drug delivery systems, paper strengthening, and fabric finishing. The increased solubility and reactivity of cyanoethyl starch make it a valuable component in the development of new materials and formulations.
The CAS Registry Mumber 9063-39-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,6 and 3 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 9063-39: (6*9)+(5*0)+(4*6)+(3*3)+(2*3)+(1*9)=102 102 % 10 = 2 So 9063-39-2 is a valid CAS Registry Number.
