393517-91-4 Usage
Molecular weight
766.02 g/mol (based on the molecular formula)
Appearance
Viscous liquid (due to the long hydrocarbon tail and multiple oxygen atoms)
Solubility
Insoluble in water (due to the long hydrocarbon tail and non-polar nature of the molecule)
Applications
Emulsifier, surfactant, and stabilizer in pharmaceuticals, personal care products, and agrochemicals (due to the presence of multiple oxygen atoms and the 4-methylbenzenesulfonate group)
Use in analytical chemistry
Stationary phase in chromatography columns (due to the long hydrocarbon tail and the phenyl group)
Versatility
Wide range of practical uses in different fields (due to its unique structure and properties)
Check Digit Verification of cas no
The CAS Registry Mumber 393517-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,3,5,1 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 393517-91:
(8*3)+(7*9)+(6*3)+(5*5)+(4*1)+(3*7)+(2*9)+(1*1)=174
174 % 10 = 4
So 393517-91-4 is a valid CAS Registry Number.

Multigram Synthesis of Well-Defined Extended Bifunctional Polyethylene Glycol (PEG) Chains
Loiseau, Francois A.,Hii, King Kuok,Hill, Alison M.
, p. 639 - 647 (2007/10/03)
A series of novel, well-defined, unsymmetrical poly(ethylene glycol) chains of the type X(OCH2-CH2)nY (where X = protecting group; Y = nucleofuge or a different protecting group; n = 3, 6, 9, 12, 15, 18, and 24) were prepared in high yields by applying orthogonal protecting groups. The purity of the compounds was fully verified by elemental and high-resolution mass spectrometry analyses.
