Starch diethylaminoethyl ether, also known as DEAE starch or quaternary ammonium starch, is a modified starch derivative used in various applications due to its cation exchange properties. It is prepared by reacting starch with diethylaminoethyl chloride, resulting in a quaternary ammonium group being attached to the starch molecule. This modification enhances its ability to interact with positively charged ions, making it useful in ion exchange chromatography for separating and purifying proteins and other biomolecules. DEAE starch is also employed in the food industry as a stabilizer and thickener, as well as in the paper industry for improving paper strength. Its cationic nature allows it to form complexes with negatively charged surfaces, which is beneficial in these applications.

Check Digit Verification of cas no

The CAS Registry Mumber 9041-94-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,4 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 9041-94:
(6*9)+(5*0)+(4*4)+(3*1)+(2*9)+(1*4)=95
95 % 10 = 5
So 9041-94-5 is a valid CAS Registry Number.
