Uses

Used in Pharmaceutical Industry:
Methoxypolyethylene glycols are used as enteric coatings for controlled release and enteric release coatings in the pharmaceutical industry. The hydrophilic PEG spacer enhances solubility and provides a protective barrier that resists degradation in the harsh acidic environment of the stomach, allowing for targeted drug delivery in the intestine.
Used in Drug Delivery Systems:
Methoxypolyethylene glycols are used in the synthesis of thermosensitive micellar cyclotriphosphazenes and amphiphilic poly(organophosphazene) for drug delivery applications. These systems can encapsulate and release drugs in a controlled manner, improving the pharmacokinetics and therapeutic efficacy of various medications.
Used in Bioconjugation and Protein Modification:
Methoxypolyethylene glycols are used in the modification of therapeutic proteins to improve their pharmacokinetics, solubility, and stability. The PEGylation of proteins can reduce immunogenicity, prolong circulation time, and enhance the therapeutic potential of biologics.

Check Digit Verification of cas no

The CAS Registry Mumber 9004-74-4 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 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 9004-74:
(6*9)+(5*0)+(4*0)+(3*4)+(2*7)+(1*4)=84
84 % 10 = 4
So 9004-74-4 is a valid CAS Registry Number.
