6943-16-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6943-16-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,4 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6943-16:
(6*6)+(5*9)+(4*4)+(3*3)+(2*1)+(1*6)=114
114 % 10 = 4
So 6943-16-4 is a valid CAS Registry Number.

Chiral Phosphoric Acid-Catalyzed Enantioselective Construction of 2,3-Disubstituted Indolines

Ma, Wei-Yang,Gelis, Coralie,Bouchet, Damien,Retailleau, Pascal,Moreau, Xavier,Neuville, Luc,Masson, Géraldine

supporting information, p. 442 - 448 (2021/01/26)

Highly enantio- and regioselective (3 + 2) formal cycloaddition of β-substituted ene- and thioenecarbamates as well as cyclic enamides with quinone diimides catalyzed by a BINOL- and SPINOL-derived phosphoric acid is reported. A wide variety of 2,3-disubstituted 2-aminoindolines, including polycyclic ones, were prepared in generally high yields (up to 98%) with moderate to complete diastereoselectivities and in most cases excellent enantioselectivities (up to 99% ee).
