116140-28-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116140-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,1,4 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 116140-28:
(8*1)+(7*1)+(6*6)+(5*1)+(4*4)+(3*0)+(2*2)+(1*8)=84
84 % 10 = 4
So 116140-28-4 is a valid CAS Registry Number.

Preparation of polyfunctional pyridines by a palladium(0)-catalyzed cross-coupling of functionalized aryl Grignard reagents

Bonnet, Véronique,Mongin, Florence,Trécourt, Francois,Quéguiner, Guy,Knochel, Paul

, p. 5717 - 5719 (2001)

Difunctionalized pyridines can be prepared by a Pd(0)-catalyzed cross-coupling of functionalized arylmagnesium compounds with chloro- or bromopyridines at temperatures as low as -40°C. An addition-elimination mechanism involving a palladate intermediate is proposed.

Synthesis and evaluation of a conditionally-silent agonist for the α7 nicotinic acetylcholine receptor

Chojnacka, Kinga,Papke, Roger L.,Horenstein, Nicole A.

, p. 4145 - 4149 (2013/07/26)

We introduce the term 'silent agonists' to describe ligands that can place the α7 nicotinic acetylcholine receptor (nAChR) into a desensitized state with little or no apparent activation of the ion channel, forming a complex that can subsequently generate
