149505-51-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 149505-51-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,5,0 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 149505-51:
(8*1)+(7*4)+(6*9)+(5*5)+(4*0)+(3*5)+(2*5)+(1*1)=141
141 % 10 = 1
So 149505-51-1 is a valid CAS Registry Number.

Catalyst- And oxidant-free electrochemical: para -selective hydroxylation of N -arylamides in batch and continuous-flow

Chen, Meng-Yi,Fang, Zheng,Guo, Kai,Lin, Xin-Xin,Liu, Cheng-Kou

, p. 6437 - 6443 (2020/11/09)

Hydroxyl compounds serve as key building blocks in the preparation of biologically active natural products and drugs. Traditionally, hydroxylation of the aromatic ring is achieved using stoichiometric amounts of oxidants, which leads to low atom-economy, undesired by-products, potential explosion risk and environmental pollution. Recently, electrosynthesis has attracted increasing attention as it employs clean electrical energy to promote redox reactions avoiding the use of oxidants. However, due to the poor mass and heat transfers of batch cells, low productivity and selectivity limit its further application. Herein, we develop a catalyst-, oxidant-, acidic solvent- and quaternary ammonium salt-free electrochemical para-selective hydroxylation of N-arylamides at room temperature in batch and continuous-flow. This proposal features excellent position control and water, air and functional group tolerance. Also, it is easy to scale up with higher productivity and selectivity using a flow electrolysis cell.
