1895922-73-2 Usage
Description
Aminooxy-PEG3-bromide HCl salt is a PEG linker containing an aminooxy group and a bromide group. The hydrophilic PEG spacer increases solubility in aqueous media. The aminooxy group can be used in bioconjugation. It reacts with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.
Check Digit Verification of cas no
The CAS Registry Mumber 1895922-73-2 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 1895922-73:
(9*1)+(8*8)+(7*9)+(6*5)+(5*9)+(4*2)+(3*2)+(2*7)+(1*3)=242
242 % 10 = 2
So 1895922-73-2 is a valid CAS Registry Number.
