19264-34-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19264-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,6 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19264-34:
(7*1)+(6*9)+(5*2)+(4*6)+(3*4)+(2*3)+(1*4)=117
117 % 10 = 7
So 19264-34-7 is a valid CAS Registry Number.

Visible-Light-Driven Oxidation of N -Alkylamides to Imides Using Oxone/H 2 O and Catalytic KBr

Mei, Chong,Hu, Yixin,Lu, Wenjun

, p. 2999 - 3005 (2018/05/25)

Imides are prepared conveniently by visible-light-driven oxidations of various N -alkylamides under mild conditions. The majority of the reactions proceed efficiently by using Oxone as the oxidant in the presence of a catalytic amount of KBr in H 2 O/CH 2 Cl 2 under irradiation by an 8 W white LED at room temperature. Experimental studies suggest that an imine, obtained from the substrate amide via a radical process, is the key intermediate.

Ultrasound-assisted catalytic synthesis of acyclic imides in the presence of p-toluenesulfonic acid under solvent-free conditions

Nasr-Esfahani, Masoud,Montazerozohori, Morteza,Filvan, Najmeh

experimental part, p. 415 - 421 (2012/06/29)

A rapid and convenient preparation of acyclic imides by the reaction of aliphatic and aromatic nitriles with acyclic carboxylic anhydride in the presence of catalytic amounts of p-toluenesulfonic acid under thermal or ultrasonic conditions is reported. The advantages of this procedure are moderate reaction times, good to excellent yields, and use of an inexpensive and ecofriendly catalyst. The reaction of nitriles with aliphatic anhydrides proceeds under thermal conditions, while they are accelerated by the use of ultrasound irradiation.

A novel one-pot synthesis of unsymmetrical acyclic imides

Habibi, Zohreh,Salehi, Peyman,Zolfigol, Mohammad Ali,Yousefi, Maryam

, p. 812 - 814 (2008/01/03)

A new and convenient method was found for the one-pot synthesis of symmetrical and unsymmetrical linear imides by reaction of aliphatic and aromatic nitriles with acyclic carboxylic anhydrides in the presence of silica sulfuric acid as an active and recyclable reagent.
