1204834-00-3 Usage
Description
Azido-PEG8-NHS ester is a popular click chemistry reagent with an azide and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
Uses
Azido-PEG8-NHS ester series of products contain an azide function on one end of a single molecular weight dPEG? spacer and a reactive group on the other end of the spacer. The dPEG? spacer is hydrophilic and non-immunogenic and improves the water solubility of the target molecule while reducing the immunogenicity and increasing the hydrodynamic volume of the target.
Check Digit Verification of cas no
The CAS Registry Mumber 1204834-00-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,8,3 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1204834-00:
(9*1)+(8*2)+(7*0)+(6*4)+(5*8)+(4*3)+(3*4)+(2*0)+(1*0)=113
113 % 10 = 3
So 1204834-00-3 is a valid CAS Registry Number.
