1895922-70-9 Usage
Description
Fmoc-aminooxy-PEG4-acid is a PEG linker with aminooxy group protected by Fmoc. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations.Check Digit Verification of cas no
The CAS Registry Mumber 1895922-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,9,5,9,2 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.Calculate Digit Verification of CAS Registry Number 1895922-70:
(9*1)+(8*8)+(7*9)+(6*5)+(5*9)+(4*2)+(3*2)+(2*7)+(1*0)=239
239 % 10 = 9
So 1895922-70-9 is a valid CAS Registry Number.
