331627-96-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 331627-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,6,2 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 331627-96:
(8*3)+(7*3)+(6*1)+(5*6)+(4*2)+(3*7)+(2*9)+(1*6)=134
134 % 10 = 4
So 331627-96-4 is a valid CAS Registry Number.

Rh(I)-Catalyzed Alkylation of ortho-C-H Bonds in Aromatic Amides with Maleimides

He, Qiyuan,Yamaguchi, Takuma,Chatani, Naoto

, p. 4544 - 4547 (2017)

An alkylation of C-H bonds with maleimides by a rhodium-catalyzed reaction of aromatic amides containing an 8-aminoquinoline moiety as the directing group is reported. Various N-substituents in the maleimide, including methyl, ethyl, cyclohexyl, benzyl, a

Copper-Catalyzed Electrochemical Selective Bromination of 8-Aminoquinoline Amide Using NH4Br as the Brominating Reagent

Fang, Ping,Huang, Yan,Mei, Tian-Sheng,Wang, Xiang-Yang,Xu, Hao-Han,Yang, Qi-Liang,Yang, Xiang

, p. 3497 - 3507 (2020/03/23)

A simple and mild protocol for copper-catalyzed bromination of quinoline at the C5 site of quinoline by anodic oxidation was developed, affording the desired remote C-H activation products with isolated yields of up to about 90%. The reaction proceeds wit

Copper-Mediated Aminoquinoline-Directed Radiofluorination of Aromatic C?H Bonds with K18F

Lee, So Jeong,Makaravage, Katarina J.,Brooks, Allen F.,Scott, Peter J. H.,Sanford, Melanie S.

supporting information, p. 3119 - 3122 (2019/01/25)

A Cu-mediated ortho-C?H radiofluorination of aromatic carboxylic acids that are protected as 8-aminoquinoline benzamides is described. The method uses K18F and is compatible with a wide range of functional groups. The reaction is showcased in t
