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 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.

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
