Description
3,6,9,12,15,18,21,24,27,30,33,36,39,42-Tetradecaoxatetratetracontane-1,44-diol is a polymeric compound consisting of ethylene glycol units and two terminal hydroxyl groups. The hydroxyl groups can react to further derivatize the compound, and the hydrophilic PEG linkers increase its water solubility in aqueous media. The water solubility properties of the PEG linker are enhanced with longer PEG chains.

Check Digit Verification of cas no
The CAS Registry Mumber 28821-35-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,2 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28821-35:
(7*2)+(6*8)+(5*8)+(4*2)+(3*1)+(2*3)+(1*5)=124
124 % 10 = 4
So 28821-35-4 is a valid CAS Registry Number.

High-purity discrete PEG-oligomer crystals allow structural insight
French, Alister C.,Thompson, Amber L.,Davis, Benjamin G.
supporting information; experimental part, p. 1248 - 1252 (2009/06/30)
To great (monodisperse) lengths: An improved synthesis of purer ethylene glycol (EG) oligomers allows access to 16- and 32-mers pure enough for multiple incorporation, and also to the longest (48-mer) discrete EG oligomer yet reported. The high purity enables the first crystallizations and hence the first glimpses of secondary 310-helical PEG structures.
