92644-16-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92644-16-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,4 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92644-16:
(7*9)+(6*2)+(5*6)+(4*4)+(3*4)+(2*1)+(1*6)=141
141 % 10 = 1
So 92644-16-1 is a valid CAS Registry Number.

Palladium/copper-catalyzed arylation of alkenes with N′-acyl arylhydrazines

Zhang, Ji-Quan,Cao, Jun,Li, Wei,Li, Shu-Min,Li, Yong-Kang,Wang, Jian-Ta,Tang, Lei

, p. 437 - 441 (2017)

A novel ligand-free palladium/copper-catalyzed Heck-type coupling reaction of alkenes and N′-acyl arylhydrazines has been developed by using air as the terminal oxidant. This protocol features wide functional group tolerance and produces highly chemoselective and regioselective products with good to excellent yields.

Selective Functionalization of Graphene at Defect-Activated Sites by Arylazocarboxylic tert-Butyl Esters

Halbig, Christian E.,Lasch, Roman,Krüll, Jasmin,Pirzer, Anna S.,Wang, Zhenping,Kirchhof, Jan N.,Bolotin, Kirill I.,Heinrich, Markus R.,Eigler, Siegfried

supporting information, p. 3599 - 3603 (2019/02/01)

The development of versatile functionalization concepts for graphene is currently in the focus of research. Upon oxo-functionalization of graphite, the full surface of graphene becomes accessible for C?C bond formation to introduce out-of-plane functional

Microwave-Assisted Rapid One-Pot Synthesis of Fused and Non-Fused Indoles and 5-[18F]Fluoroindoles from Phenylazocarboxylates

Krüll, Jasmin,Hubert, Anja,Nebel, Natascha,Prante, Olaf,Heinrich, Markus R.

supporting information, p. 16174 - 16178 (2017/10/30)

Substituted indoles can be prepared from phenylazocarboxylates through a rapid one-pot sequence featuring a microwave-assisted Fischer indole synthesis as a key step. Considering that the phenylazocarboxylates may beforehand be modified by mild nucleophilic aromatic substitution, including the introduction of [18F]fluoride, the overall strategy offers an attractive new access to 5-[18F]fluoroindoles.
