1807512-38-4 Usage
Description
Acid-PEG6-mono-methyl ester is a PEG linker containing a terminal carboxylic acid and a methyl ester group. The carboxylic acid can react with primary amine groups in the presence of activators such as EDC and HATU to form stable amide bonds. The hydrophilic PEG linkers increase the water solubility of a compound in aqueous media. The water solubility properties of the PEG chain are enhanced with longer PEG chains.
Check Digit Verification of cas no
The CAS Registry Mumber 1807512-38-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,0,7,5,1 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1807512-38:
(9*1)+(8*8)+(7*0)+(6*7)+(5*5)+(4*1)+(3*2)+(2*3)+(1*8)=164
164 % 10 = 4
So 1807512-38-4 is a valid CAS Registry Number.
