Check Digit Verification of cas no

The CAS Registry Mumber 38584-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,5,8 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38584-43:
(7*3)+(6*8)+(5*5)+(4*8)+(3*4)+(2*4)+(1*3)=149
149 % 10 = 9
So 38584-43-9 is a valid CAS Registry Number.

Protecting-group-free synthesis of hydroxyesters from amino alcohols

Joseph-Valcin, Eve-Marline,Lebel, Hélène,Reynard, Guillaume

supporting information, p. 10938 - 10941 (2020/10/02)

The synthesis of hydroxyesters from carboxylic acids and unprotected amino alcohols in both continuous flow and batch processes is reported. The formation of a transient diazonium species with a dinitrite reagent is key in this transformation. The reaction conditions are compatible with a variety of functional groups.

Kinetic Modeling of the Nickel-Catalyzed Esterification of Amides

Weires, Nicholas A.,Caspi, Daniel D.,Garg, Neil K.

, p. 4381 - 4385 (2017/07/24)

Nickel-catalyzed coupling reactions provide exciting tools in chemical synthesis. However, most methodologies in this area require high catalyst loadings, which commonly range from 10-20 mol % nickel. Through an academic-industrial collaboration, we demonstrate that kinetic modeling can be used strategically to overcome this problem, specifically within the context of the Ni-catalyzed conversion of amides to esters. The successful application of this methodology to a multigram-scale coupling, using only 0.4 mol % Ni, highlights the impact of this endeavor.

4-(N,N -dimethylamino)pyridine hydrochloride as a recyclable catalyst for acylation of inert alcohols: Substrate scope and reaction mechanism

Liu, Zhihui,Ma, Qiaoqiao,Liu, Yuxiu,Wang, Qingmin

supporting information, p. 236 - 239 (2014/01/23)

4-(N,N-Dimethylamino)pyridine hydrochloride (DMAP·HCl), a DMAP salt with the simplest structure, was used as a recyclable catalyst for the acylation of inert alcohols and phenols under base-free conditions. The reaction mechanism was investigated in detail for the first time; DMAP·HCl and the acylating reagent directly formed N-acyl-4-(N′,N′-dimethylamino) pyridine chloride, which was attacked by the nucleophilic substrate to form a transient intermediate that released the acylation product and regenerated the DMAP·HCl catalyst.
