Sephadex is a type of gel made from cross-linked dextran, a polysaccharide derived from sucrose, and is widely used in various applications such as chromatography, gel filtration, and as a carrier in drug delivery systems. Sephadex 2-hydroxypropyl ether, also known as Sephadex LH-20, is a specific variant of Sephadex that has been modified with 2-hydroxypropyl groups. This modification enhances its hydrophilic properties, making it suitable for use in aqueous solutions and improving its compatibility with a broader range of biomolecules. Sephadex LH-20 is particularly useful in the separation and purification of compounds based on their size and polarity, and it is often employed in the isolation of natural products, peptides, and other biologically active molecules. Its unique properties allow for efficient and gentle separation processes, preserving the integrity of the separated compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 9049-22-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 9049-22:
(6*9)+(5*0)+(4*4)+(3*9)+(2*2)+(1*2)=103
103 % 10 = 3
So 9049-22-3 is a valid CAS Registry Number.
