Check Digit Verification of cas no

The CAS Registry Mumber 20983-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,8 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20983-67:
(7*2)+(6*0)+(5*9)+(4*8)+(3*3)+(2*6)+(1*7)=119
119 % 10 = 9
So 20983-67-9 is a valid CAS Registry Number.

Diarylamine Synthesis via Desulfinylative Smiles Rearrangement

Sephton, Thomas,Large, Jonathan M.,Butterworth, Sam,Greaney, Michael F.

, p. 1132 - 1135 (2022/02/09)

Diarylamines are obtained directly from sulfinamides through a novel rearrangement sequence. The transformation is transition metal-free and proceeds under mild conditions, providing facile access to highly sterically hindered diarylamines that are otherw

Magnetic acyclovir-copper nanoparticle: DFT study and application as an efficient, magnetically separable and recyclable catalyst for N-arylation of amines under green condition

Heydari, Akbar,Pazoki, Farzane

, (2020/10/06)

A copper(I)‐acyclovir complex supported on magnetic was designed and successfully synthesized. Catalytic activity and stability of two structures of copper(I)‐acyclovir complex supported on magnetic were investigated by the theoretical method. The more active and stable copper(I)‐acyclovir complex supported on magnetic was applied as a catalyst for C–N cross‐coupling reaction with high yield in a deep eutectic solvent (DES) as a green solvent. Also, these nanoparticles could be easily recovered and reused for new rounds of reaction without any considerable loss in catalytic activity.

Recyclable bimetallic CuMoO4 nanoparticles for C-N cross-coupling reaction under mild conditions

Panigrahi, Reba,Panda, Subhalaxmi,Behera, Pradyota Kumar,Sahu, Santosh Kumar,Rout, Laxmidhar

supporting information, p. 19274 - 19278 (2019/12/24)

Herein we disclosed inexpensive copper(ii) bimetallic CuMoO4 nanoparticles for the C-N cross-coupling reaction of alkyl and aryl amines with haloarenes. The reaction proceeds under mild and ligand free conditions. The catalyst is recyclable and effective for a wide range of amines and haloarenes. Here, the efficiency of the Cu(ii) catalyst is increased by doping molybdenum metal. The bimetallic nanoparticles are anticipated to proceed via normal oxidative addition and reductive eliminations.
