294642-61-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 294642-61-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,4,6,4 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 294642-61:
(8*2)+(7*9)+(6*4)+(5*6)+(4*4)+(3*2)+(2*6)+(1*1)=168
168 % 10 = 8
So 294642-61-8 is a valid CAS Registry Number.

Copper-Salt-Promoted Carbocyclization Reactions of α-Bromo- N -arylacylamides

Chuang, Che-Ping,Chen, Ying-Yu,Chuang, Tsung-Han,Yang, Cheng-Hao

, p. 1273 - 1284 (2017)

A mild and convenient synthetic method for oxindoles and α-arylacylamides bearing an all carbon quaternary stereocenter from the readily available α-bromo-N-arylacylamides has been developed. This Cu(acac)2/Phen-promoted radical cyclization rea

Visible-Light-Driven Aryl Migration and Cyclization of α-Azido Amides

Liang, Siyu,Wei, Kaijie,Lin, Yajun,Liu, Tuming,Wei, Dian,Han, Bing,Yu, Wei

supporting information, p. 4527 - 4531 (2021/06/28)

This paper reports two new visible-light-promoted radical reactions of α-azido amides. By catalysis of [Ir(ppy)2(dtbbpy)]PF6 with i-Pr2NEt as the reducing agent, N-aryl α-azido tertiary amides were first converted to the corresponding aminyl radicals through reduction of the azido group; the aminyl radicals then underwent N-to-N aryl migration to give α-anilinyl-functionalized amides. α-Azido secondary amides, on the other hand, reacted with the solvent ethanol and i-Pr2NEt to afford the imidazolinone products.
