Check Digit Verification of cas no

The CAS Registry Mumber 1356470-27-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,4,7 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1356470-27:
(9*1)+(8*3)+(7*5)+(6*6)+(5*4)+(4*7)+(3*0)+(2*2)+(1*7)=163
163 % 10 = 3
So 1356470-27-3 is a valid CAS Registry Number.

Direct Amidation of Carboxylic Acids with Nitroarenes

Wang, Shao-Peng,Cheung, Chi Wai,Ma, Jun-An

, p. 13922 - 13934 (2019/11/03)

N-Aryl amides are an important class of compounds in pharmaceutical and agrochemical chemistry. Rapid and low-cost synthesis of N-aryl amides remains in high demand. Herein, we disclose an operationally simple process to access N-aryl amides directly from readily available nitroarenes and carboxylic acids as coupling substrates. This method involves the in situ activation of carboxylic acids to acyloxyphosphonium salt for one-pot amidation, without the need for isolation of the corresponding synthetic intermediates. Furthermore, the ease of preparation and workup allow the quick and efficient synthesis of a wide range of N-aryl amides, including several amide-based druglike and agrochemical molecules.

Copper-catalyzed direct transformation of secondary allylic and benzylic alcohols into azides and amides: An efficient utility of azide as a nitrogen source

Rokade, Balaji V.,Gadde, Karthik,Prabhu, Kandikere Ramaiah

, p. 2706 - 2717 (2015/04/27)

A mild and convenient method for the synthesis of amides has been explored by using secondary alcohols, Cu(ClO4)2·6H2O as a catalyst, and trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) at ambient temperature. This method has been successfully adapted to the preparation of azides directly from their corresponding alcohols and offers excellent chemoselectivity in the formation of ω-halo azides and the azidation of allylic alcohols in the presence of a benzyl alcohol moiety. In addition, this strategy provides an opportunity to synthesize azides that can serve as precursors to β-amino acids. A mild and convenient method for the synthesis of amides has been explored by using secondary alcohols, Cu(ClO4)2·6H2O as a catalyst, and trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) at ambient temperature. This method has also been adapted to the preparation of azides directly from their corresponding alcohols.

Iron-catalyzed C-H and C-C bond cleavage: A direct approach to amides from simple hydrocarbons

Qin, Chong,Zhou, Wang,Chen, Feng,Ou, Yang,Jiao, Ning

supporting information; experimental part, p. 12595 - 12599 (2012/01/15)

Something functional: The title reaction proceeds in the presence of azide and water to deliver amides in high yields, and it can be used in a ring-expansion strategy to generate lactams. A mechanism is proposed based on experimental results. This reaction offers a new approach to functionalizing simple and readily available hydrocarbons. DDQ=2,3-dichloro-5,6-dicyano-1,4- benzoquinone. Copyright
