311806-85-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 311806-85-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,1,8,0 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 311806-85:
(8*3)+(7*1)+(6*1)+(5*8)+(4*0)+(3*6)+(2*8)+(1*5)=116
116 % 10 = 6
So 311806-85-6 is a valid CAS Registry Number.

Thermodynamically controlled cyclisation reactions with double phenylsulfanyl migration

Carlisle, Julie,Fox, David J.,Warren, Stuart

, p. 2696 - 2697 (2003)

Enantiomerically enriched C2-symmetric tetrols were synthesised by a route involving a 'self-metathesis' reaction with Grubbs' second-generation ruthenium catalyst; these tetrols produced interesting bicyclic products when rearranged under acid

Asymmetric synthesis of tetrahydrofurans by competitive [1,2]-phenylsulfanyl (PhS) migrations under thermodynamic control

Caggiano, Lorenzo,Fox, David J.,House, David,Jones, Zoe A.,Kerr, Fraser,Warren, Stuart

, p. 2634 - 2645 (2007/10/03)

Asymmetric synthesis of tetrahydrofurans (THF) by competitive [1,2]-phenylsulfanyl (PhS) migrations under thermodynamic control was discussed. Triols were prepared in enantiomerically enriched form by a short route that included a Sharpless asymmetric dihydroxylation. Treatment of these triols with toluene-p-sulfonic acid gave THFs as thermodynamic products.
