Check Digit Verification of cas no

The CAS Registry Mumber 140165-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,6 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140165-83:
(8*1)+(7*4)+(6*0)+(5*1)+(4*6)+(3*5)+(2*8)+(1*3)=99
99 % 10 = 9
So 140165-83-9 is a valid CAS Registry Number.

XtalFluor-E mediated proto-functionalization of: N -vinyl amides: Access to N -acetyl N, O -acetals

Yi,Gholami,Morrow,Borhan

supporting information, p. 9570 - 9574 (2017/11/30)

XtalFluor-E has been extensively used in a broad range of reactions in the past few years. Here we report its use with protic nucleophiles in a catalytic manner for the in situ generation of protons that lead to the proto-functionalization of activated ol

Nickel-Catalyzed Synthesis of Enamides and Enecarbamates via Isomerization of Allylamides and Allylcarbamates

Halli, Juliette,Kramer, Philipp,Bechthold, Maren,Manolikakes, Georg

supporting information, p. 3321 - 3324 (2015/11/03)

A single-component, air-stable nickel precatalyst can catalyze the isomerization of allylamides for the synthesis of enamides. The scope of the reaction encompasses various substituted allylamides and allylcarbamates as well as homoallylamides. The reaction can be performed on a multigram-scale without specialized glove-box equipment or Schlenk techniques.

[Pd(μ-Br)(PtBu3)]2 as a highly active isomerization catalyst: Synthesis of enol esters from allylic esters

Mamone, Patrizia,Gruenberg, Matthias F.,Fromm, Andreas,Khan, Bilal A.,Goossen, Lukas J.

supporting information; experimental part, p. 3716 - 3719 (2012/09/08)

The dimeric Pd(I)-complex [Pd(μ-Br)(PtBu3)] 2 was found to be highly active for catalyzing double-bond migration in various substrates such as unsaturated ethers, alcohols, amides, and arenes, under mild conditions. It efficiently mediates the conversion of allylic esters into enol esters, rather than inserting into the allylic C-O bond. The broad applicability of this reaction was demonstrated with the synthesis of 22 functionalized enol esters.
