Check Digit Verification of cas no

The CAS Registry Mumber 439695-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,6,9 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 439695-64:
(8*4)+(7*3)+(6*9)+(5*6)+(4*9)+(3*5)+(2*6)+(1*4)=204
204 % 10 = 4
So 439695-64-4 is a valid CAS Registry Number.

Rhodium-catalyzed asymmetric arylation of N -(tert -butanesulfinyl)imines with sodium tetraarylborates

Reddy, Leleti Rajender,Gupta, Aditya P.,Villhauer, Eric,Liu, Yugang

experimental part, p. 1095 - 1100 (2012/03/12)

A diastereoselective rhodium-catalyzed arylation of N-(tert-butanesulfinyl) imines with sodium tetraarylborates is described. This method is general for constructing various chiral α-branched amines and 2-substituted pyrrolidines with high diastereoselectivity. A practical asymmetric approach to access chiral amines has been developed involving the use of air-stable Rh catalysts and reagents and in the absence of an external ligand.

Asymmetric Rh(I)-catalyzed addition of MIDA boronates to N-Tert -butanesulfinyl aldimines: Development and comparison to trifluoroborates

Brak, Katrien,Ellman, Jonathan A.

supporting information; experimental part, p. 3147 - 3150 (2010/07/09)

The Rh(I)-catalyzed addition of alkenyl and aryl MIDA boronates to N-tert-butanesulfinyl aromatic and aliphatic imines proceeds in good yields (up to 99%) and with very high selectivity (98:2 to >99:1). In comparison to trifluoroborates, higher yields and

Asymmetric synthesis of diarylmethylamines by diastereoselective addition of organometallic reagents to chiral N-tert-butanesulfinimines: Switchover of diastereofacial selectivity

Plobeck, Niklas,Powell, David

, p. 303 - 310 (2007/10/03)

Diastereoselective addition of organometallic reagents to chiral N-tert-butanesulfinimines gave alkylated adducts in high yields and diastereoselectivities. Cleavage of the chiral auxiliary under mildly acidic conditions gave diarylmethylamines in high yi

Asymmetric synthesis of cetirizine dihydrochloride

Pflum, Derek A,Krishnamurthy, Dhileepkumar,Han, Zhengxu,Wald, Stephen A,Senanayake, Chris H

, p. 923 - 926 (2007/10/03)

Practical route technology for the preparation of (S)-cetirizine·2HCl via diastereoselective organometallic addition to N-tert-butanesulfinyl aldimines is disclosed.
