290827-93-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 290827-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,8,2 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 290827-93:
(8*2)+(7*9)+(6*0)+(5*8)+(4*2)+(3*7)+(2*9)+(1*3)=169
169 % 10 = 9
So 290827-93-9 is a valid CAS Registry Number.

Fluorous phosphines and phosphine oxides

-

, (2008/06/13)

A method of increasing the fluorous nature of a compound includes the step of reacting the compound with or tagging the compound with at least one of a second compound having the formula: wherein R is an alkyl group or an aryl group, n is 1, 2 or 3 and Rs is a spacer group and Rf is a branched fluorous group. A chemical compound having the general formula: wherein n, Rs and Rf are defined above.

Separation of "light fluorous" reagents and catalysts by fluorous solid-phase extraction: Synthesis and study of a family of triarylphosphines bearing linear and branched fluorous tags

Zhang,Luo,Curran

, p. 8866 - 8873 (2007/10/03)

Practical syntheses of new triarylphosphines bearing both linear and branched fluorous tags (Rf) are reported. The phosphines have one, two, or all three aryl rings bearing fluorous tags: (Ph)3-nP(C6H4 (CH2)mRf)n. Fluorous-organic partition coefficients have been measured and the retention properties of both the phosphines and the derived phosphine oxides on fluorous reverse phase silica have been studied. While applications relying on liquid-liquid extractive separations of these phosphines may be limited to those bearing three fluorous chains, the technique of solid phase extraction should be broadly applicable to phosphines, phosphine oxides, and derived metal complexes. A parallel platinum-catalyzed allylation of aldehydes with fluorous allyl stannanes illustrates the usefulness of the new fluorous ligands in small-scale synthesis.
