1292268-13-3 Usage
Description
N-Boc-PEG7-alcohol is a PEG linker containing a hydroxyl group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The Boc group can be deprotected under mild acidic conditions to form the free amine.
Check Digit Verification of cas no
The CAS Registry Mumber 1292268-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,2,6 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1292268-13:
(9*1)+(8*2)+(7*9)+(6*2)+(5*2)+(4*6)+(3*8)+(2*1)+(1*3)=163
163 % 10 = 3
So 1292268-13-3 is a valid CAS Registry Number.

Modular synthesis of bifunctional linkers for materials science
Moreau, Julie,Marchand-Brynaert, Jacqueline
, p. 1641 - 1644 (2011/05/03)
A practical synthesis of α,ω-bifunctional linkers is described that is based on three building blocks, namely, thioctic acid, a spacer-arm of seven ethylene glycol units, and a functional motif dedicated to the selective immobilization of purposely tagged proteins. Such representative motifs are biotin, haloacetamide, maleimide, and nitrilotriacetic acid derivatives. The building blocks are connected through alkyl, amide, and/or carbamate linkages. Copyright
