57197-16-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57197-16-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,9 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57197-16:
(7*5)+(6*7)+(5*1)+(4*9)+(3*7)+(2*1)+(1*6)=147
147 % 10 = 7
So 57197-16-7 is a valid CAS Registry Number.

Lewis Acid-Mediated Site-Selective Synthesis of Oxygenated Biaryls from Methoxyphenols and Electron-Rich Arenes

Sharma, Shivangi,Parumala, Santosh Kumar Reddy,Peddinti, Rama Krishna

, p. 9367 - 9383 (2017/09/22)

A rapid, efficient, and metal-free Lewis acid-mediated methodology has been developed for the site-selective synthesis of unsymmetrical oxygenated biaryls. This simple and efficient methodology furnished highly oxygenated and functionalized unsymmetrical biaryls in good to excellent yields by the direct oxidative coupling of electron-rich arenes to the α-position of carbonyl functionality of in situ generated masked benzoquinones.

Lewis acid catalyzed [3+2] coupling of indoles with quinone monoacetals or quinone imine ketal

Shu, Chang,Liao, Li-Hua,Liao, Yi-Jun,Hu, Xiao-Yan,Zhang, Yong-Hong,Yuan, Wei-Cheng,Zhang, Xiao-Mei

supporting information, p. 4467 - 4471 (2014/08/05)

The one-pot synthesis of benzofuroindolines and tetrahydroindolo[2,3-b] indoles was accomplished through a mild and concise [3+2] coupling of indoles and quinone monoacetals or quinone imine ketal promoted by a Lewis acid. A wide variety of benzofuroindolines and tetrahydroindolo[2,3-b]indoles were prepared in moderate to good yields. Copyright

Short, enantioselective total syntheses of (-)-8-demethoxyrunanine and (-)-cepharatines A, C, and D

Chuang, Kangway V.,Navarro, Raul,Reisman, Sarah E.

supporting information; scheme or table, p. 9447 - 9451 (2011/11/07)

All together! A unified synthetic strategy has resulted in the first enantioselective total syntheses of the natural products 8-demethoxyrunanine and cepharatines A, C, and D.
