Check Digit Verification of cas no

The CAS Registry Mumber 1340546-31-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,5,4 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1340546-31:
(9*1)+(8*3)+(7*4)+(6*0)+(5*5)+(4*4)+(3*6)+(2*3)+(1*1)=127
127 % 10 = 7
So 1340546-31-7 is a valid CAS Registry Number.

Visible-Light-Mediated Catalytic Hydroacylation of Dialkyl Azodicarboxylates by Graphite Flakes

Koutoulogenis, Giorgos S.,Kokotou, Maroula G.,Voutyritsa, Errika,Limnios, Dimitris,Kokotos, Christoforos G.

, p. 1760 - 1763 (2017)

A novel and efficient metal-free catalyzed hydroacylation of dialkyl azodicarboxylates is reported. Graphite flakes were found to be the most efficient catalyst among other carbon-based materials to promote this reaction. This unprecedented catalytic activity can be expanded into a wide substrate scope of aliphatic aldehydes bearing various functional groups, leading to the corresponding products in good to excellent yields.

A facile, one-pot procedure for the conversion of aromatic aldehydes to esters, as well as thioesters and amides, via acyl hydrazide intermediates

Maruani, Antoine,Lee, Maximillian T. W.,Watkins, George,Akhbar, Ahmed R.,Baggs, Henry,Shamsabadi, André,Richards, Daniel A.,Chudasama, Vijay

, p. 3372 - 3376 (2016/01/16)

Herein we present an efficient method for the synthesis of esters from aromatic aldehydes via readily accessible acyl hydrazides. The developed reaction protocol is shown to be tolerant of a range of aromatic aldehydes, bearing various functionalities, as well as being amenable to the synthesis of thioesters and amides.

Acyl hydrazides as acyl donors for the synthesis of diaryl and aryl alkyl ketones

Akhbar, Ahmed R.,Chudasama, Vijay,Fitzmaurice, Richard J.,Powell, Lyn,Caddick, Stephen

supporting information, p. 743 - 746 (2014/01/06)

In this communication we describe a novel strategy for the formation of valuable diaryl and aryl alkyl ketones from acyl hydrazides. A wide variety of ketones are prepared and the mild reaction conditions allow for the use of a range of functionalities, especially in the synthesis of diaryl ketones.
