71650-76-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71650-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,5 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 71650-76:
(7*7)+(6*1)+(5*6)+(4*5)+(3*0)+(2*7)+(1*6)=125
125 % 10 = 5
So 71650-76-5 is a valid CAS Registry Number.

Reaction discovery using acetylene gas as the chemical feedstock accelerated by the stop-flow micro-tubing reactor system

Xue, Fei,Deng, Hongping,Xue, Chengwen,Mohamed, Dara Khairunnisa Binte,Tang, Karen Yuanting,Wu, Jie

, p. 3623 - 3627 (2017/07/11)

Acetylene gas has been applied as a feedstock under transition-metal catalysis and photo-redox conditions to produce important chemicals including terminal alkynes, fulvenes, and fluorinated styrene compounds. The reaction discovery process was accelerated through the use of stop-flow micro-tubing reactors. This reactor prototype was developed by joining elements from both continuous micro-flow and conventional batch reactors, which was convenient and effective for gas/liquid reaction screening. Notably, the developed transformations were either inefficient or unsuccessful in conventional batch reactors. Its success relies on the unique advantages provided by this stop-flow micro-tubing reactor system.
