1373935-52-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1373935-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,9,3 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1373935-52:
(9*1)+(8*3)+(7*7)+(6*3)+(5*9)+(4*3)+(3*5)+(2*5)+(1*2)=184
184 % 10 = 4
So 1373935-52-4 is a valid CAS Registry Number.

Facile synthesis of nonsymmetrical heteroaryl-substituted triarylmethanes: Via the FeCl3·6H2O-catalyzed two-step Friedel-Crafts-type reaction

Ruengsangtongkul,Taprasert,Sirion,Jaratjaroonphong

, p. 8493 - 8502 (2016/09/28)

The FeCl3·6H2O-catalyzed three-component aza-Friedel-Crafts reaction of aromatic/heteroaromatic compounds, aromatic aldehydes and tert-butyl carbamate was reported. The subsequent Friedel-Crafts-type alkylation of the resulting tert-

NIS-assisted aza-Friedel-Crafts reaction with α-carbamoysulfides as precursors of N-carbamoylimines

George, Nicolas,Bekkaye, Mathieu,Alix, Aurelien,Zhu, Jieping,Masson, Geraldine

supporting information, p. 3621 - 3625 (2014/04/03)

A general and practical N-iodosuccinimide (NIS)-promoted aza-Friedel-Crafts reaction of various aromatic nucleophiles with N-acylimines generated in situ from α-amidosulfides to give a rapid access to highly functionalized amines is described. The newly developed methodology is very mild, fast, efficient, and complementary.

Ruthenium porphyrin catalyzed friedel-crafts type reaction of arenes with imines

Terada, Takuma,Kurahashi, Takuya,Matsubara, Seijiro

, p. 2415 - 2419 (2012/11/13)

Cationic ruthenium porphyrin complex was found to be an efficient catalyst for the Friedel-Crafts type reaction of arenes with imines. The use of a structurally rigid tetradentate porphyrin as the equatorial ligand and weakly coordinating axial ligand is the key to bring out the catalytic reactivity of ruthenium for the reaction.
