Check Digit Verification of cas no

The CAS Registry Mumber 1438558-82-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,5,5 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1438558-82:
(9*1)+(8*4)+(7*3)+(6*8)+(5*5)+(4*5)+(3*8)+(2*8)+(1*2)=197
197 % 10 = 7
So 1438558-82-7 is a valid CAS Registry Number.

Pd(II)-Catalyzed Arylation/Oxidation of Benzylic C-H of 8-Methylquinolines: Access to 8-Benzoylquinolines

Wang, Wenrong,Fu, Xiaoqing,Cai, Yuchen,Cheng, Li,Yao, Changsheng,Wang, Xiangshan,Li, Tuan-Jie

, p. 15423 - 15432 (2021/10/20)

An efficient access to 8-benzoylquinoline was developed by a sequential arylation/oxidation of 8-methylquinolines with aryl iodides in the presence of Pd(OAc)2. This transformation demonstrates good tolerance of a wide range of functional groups on aryl iodides, providing good to excellent yields of 8-benzoylquinolines.

Rhodium-Catalyzed Interconversion of Quinolinyl Ketones with Boronic Acids via C-C Bond Activation

Dennis, Joseph M.,Compagner, Chad T.,Dorn, Stanna K.,Johnson, Jeffrey B.

, p. 3334 - 3337 (2016/07/26)

A rhodium-catalyzed cross-coupling of aryl and aliphatic quinolinyl ketones with boronic acids has been developed. Proceeding via quinoline-directed carbon-carbon σ bond activation, the transformation demonstrates tolerance of a range of functional groups

Direct exchange of a ketone methyl or aryl group to another aryl group through ciC bond activation assisted by rhodium chelation

Wang, Jingjing,Chen, Weiqiang,Zuo, Sujing,Liu, Lu,Zhang, Xinrui,Wang, Jianhui

supporting information, p. 12334 - 12338 (2013/02/23)

Swapped: Commercially available quinolinone derivatives (1 or 2, see scheme) were reacted with arylboronic acids in the presence of a RhI complex to give aryl(quinolin-8-yl)methanone products 3 in medium to good yields. A mechanism that involves the in situ oxidation of RhI to RhIII by O2 in the presence of CuI was proposed. Copyright
