Check Digit Verification of cas no

The CAS Registry Mumber 82079-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,7 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82079-40:
(7*8)+(6*2)+(5*0)+(4*7)+(3*9)+(2*4)+(1*0)=131
131 % 10 = 1
So 82079-40-1 is a valid CAS Registry Number.

Flexible C2-symmetric bis-sulfoxides as ligands in enantioselective 1,4-addition of boronic acids to electron-deficient alkenes

Khiar, Noureddine,Salvador, Alvaro,Valdivia, Victoria,Chelouan, Ahmed,Alcudia, Ana,Alvarez, Eleuterio,Fernandez, Inmaculada

, p. 6510 - 6521 (2013/07/26)

The application of acyclic C2-symmetric chelating bis-sulfoxide ligands in the Rh(I)-catalyzed enantioselective 1,4-addition of boronic acids to electron-deficient alkenes is reported. Among the acyclic ethane-bridged bis-sulfoxides tested, the

Organocatalytic asymmetric synthesis of sulfoxides from sulfenic acid anions mediated by a cinchona -derived phase-transfer reagent

Gelat, Fabien,Jayashankaran, Jayadevan,Lohier, Jean-Francois,Gaumont, Annie-Claude,Perrio, Stephane

, p. 3170 - 3173 (2011/08/06)

Preliminary results concerning a conceptually novel route to chiral sulfoxides based on the asymmetric alkylation of sulfenate salts with alkyl halides mediated by a chiral phase-transfer catalyst are described. As a representative example, o-anisyl methyl sulfoxide was produced in 96% yield and with an enantiomeric excess of 58% using commercial cinchonidinium derivative 2a.

Highly enantioselective oxidation of sulfides to sulfoxides by a new oxaziridinium salt

Del Rio,Wang,Achab,Bohe

, p. 2265 - 2268 (2008/02/04)

The new oxaziridinium salt 5 (R2 = TBDPS) is an effective reagent for the highly enantioselective oxidation of sulfides to sulfoxides with up to >99% ee and good yields. As such, it represents a new valuable nonmetallic alternative to the existing methods for asymmetric sulfoxidation.
