474922-20-8 Usage
Description
DSPE-PEG-CH2COOH, MW 2,000 is a PEG polymer with DSPE and carboxylic acid end groups. The DSPE-PEGs have been FDA approved for medical applications. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The -COOH group can react with primary amines in the presence of activator, such as EDC or HATU, to form a stable amide bond.Check Digit Verification of cas no
The CAS Registry Mumber 474922-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,9,2 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.Calculate Digit Verification of CAS Registry Number 474922-20:
(8*4)+(7*7)+(6*4)+(5*9)+(4*2)+(3*2)+(2*2)+(1*0)=168
168 % 10 = 8
So 474922-20-8 is a valid CAS Registry Number.
