Check Digit Verification of cas no

The CAS Registry Mumber 134822-96-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,2 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134822-96:
(8*1)+(7*3)+(6*4)+(5*8)+(4*2)+(3*2)+(2*9)+(1*6)=131
131 % 10 = 1
So 134822-96-1 is a valid CAS Registry Number.

Pd-Catalyzed Etherification of Nitroarenes

Matsushita, Naoki,Kashihara, Myuto,Formica, Michele,Nakao, Yoshiaki

, p. 2209 - 2214 (2021)

The Pd-catalyzed etherification of nitroarenes with arenols has been achieved using a new rationally designed ligand. Mechanistic insights were used to design the ligand so that both the oxidative addition and reductive elimination steps of a plausible catalytic cycle were facilitated. The catalytic system established here provides direct access to a range of unsymmetrical diaryl ethers from nitroarenes.

The coupling reactions of aryl halides and phenols catalyzed by palladium and MOP-type ligands

Zhang, Yi,Ni, Gang,Li, Chengjun,Xu, Sheng,Zhang, Zhaoguo,Xie, Xiaomin

, p. 4927 - 4932 (2015/06/23)

Palladium-catalyzed coupling reactions of aryl halides and phenols are described employing the bulky and electron-rich MOP-type ligands. When K3PO4 was used as base and toluene as solvent, the catalyst system exhibited high efficiency for the coupling reaction of the activated aryl halides. When NaH was used as base and o-xylene as solvent, unactivated aryl halides can be used as substrates.
