50789-50-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50789-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,7,8 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 50789-50:
(7*5)+(6*0)+(5*7)+(4*8)+(3*9)+(2*5)+(1*0)=139
139 % 10 = 9
So 50789-50-9 is a valid CAS Registry Number.

Diastereoselective addition of α-metalated sulfoxides to imines revisited: Mechanism, computational studies, and the effect of external chiral ligands

Pedersen, Brian,Rein, Tobias,Sotofte, Inger,Norrby, Per-Ola,Tanner, David

, p. 885 - 898 (2007/10/03)

Some new results on asymmetric synthesis via the addition of α-metalated methyl tolyl sulfoxides to imines are presented. Good diastereoselectivity (up to >98% d.e. for product 3g) can be obtained under conditions of kinetic control (short reaction time,

Diastereoselective Kinetically and Thermodynamically Controlled Additions of (R)-(+)-Methyl p-Tolyl Sulphoxide Anion to Imines (Tolyl = C6H4Me)

Pyne, Stephen G.,Dikic, Branko

, p. 826 - 827 (2007/10/02)

The anion of (R)-(+)-methyl p-tolyl sulphoxide reacts diastereoselectively with imines to give chiral β-amino sulphoxides.
