51924-66-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51924-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,2 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 51924-66:
(7*5)+(6*1)+(5*9)+(4*2)+(3*4)+(2*6)+(1*6)=124
124 % 10 = 4
So 51924-66-4 is a valid CAS Registry Number.

Continuous Flow Liquid-Liquid Separation Using a Computer-Vision Control System: The Bromination of Enaminones with N -Bromosuccinimide

O'Brien, Matthew,Cooper, Dennis

, p. 164 - 168 (2015/12/26)

Incorporating open-source software components (Python, OpenCV), a computer-vision system was used to control the interface level in a gravity-based inline liquid-liquid separation device. This was used in the continuous flow bromination of a series of enaminone substrates. The main byproduct of the reaction, succinimide, was efficiently extracted into the aqueous stream, providing clean products without the need for further purification.

α-bromination of β-enamino compounds using K-10

Braibante,Braibante,Rosso,Da Roza

, p. 1935 - 1937 (2007/10/03)

A series of α-bromo 3-amino-5,5-dimethylcyclohex-2-en-1-ones 2a-g and α-bromo β-enamino compounds 4a, b have been conveniently prepared using NBS supported on montmorillonite (K-10). Other reaction conditions such as di-tert-butyl peroxide/NBS/CCl4/
