1314378-12-5 Usage
Description
Bis-PEG4-PFP ester is a PEG linker with two terminal PFP ester moieties. PFP esters are activated esters that react with primary amines to form amide bonds. They have been found to be more stable than other amine reactive groups because they are less likely to undergo hydrolysis. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media.
Check Digit Verification of cas no
The CAS Registry Mumber 1314378-12-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,3,7 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1314378-12:
(9*1)+(8*3)+(7*1)+(6*4)+(5*3)+(4*7)+(3*8)+(2*1)+(1*2)=135
135 % 10 = 5
So 1314378-12-5 is a valid CAS Registry Number.
