Check Digit Verification of cas no

The CAS Registry Mumber 1443788-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,7,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1443788-20:
(9*1)+(8*4)+(7*4)+(6*3)+(5*7)+(4*8)+(3*8)+(2*2)+(1*0)=182
182 % 10 = 2
So 1443788-20-2 is a valid CAS Registry Number.

A Convenient Strategy for Remote C-H Bond Halogenation of 8-Aminoquinolines in the C5 Position

Chen, Xiang-Xiang,Wang, Jia-Xin,Ren, Jiang-Tao,Xie, Hu,Zhao, Yanxia,Li, Ya-Min,Sun, Meng

, p. 1840 - 1844 (2017)

A highly efficient and convenient strategy has been developed for remote C-H bond halogenation of 8-aminoquinolines in good to excellent yields under transition-metal-free conditions. The reaction tolerates a variety of functional groups and can potentially be scaled up.

Cobalt(II)-catalyzed chelation-assisted C-H iodination of aromatic amides with I2

Kommagalla, Yadagiri,Yamazaki, Ken,Yamaguchi, Takuma,Chatani, Naoto

, p. 1359 - 1362 (2018)

The cobalt-catalyzed chelation-assisted iodination of aromatic amides using molecular I2 as an iodinating reagent is reported. 8-Amino-5-chloroquinoline functions as an efficient directing group. This mild and air stable catalytic system shows a wide functional group tolerance and improved synthetic accessibility.

Transition-metal-free oxidative C5 C-H-halogenation of 8-aminoquinoline amides using sodium halides

Wang, Ying,Wang, Yang,Jiang, Kai,Zhang, Qian,Li, Dong

, p. 10180 - 10184 (2016)

A simple and efficient transition-metal-free oxidative halogenation (Cl, Br) of the C5 C-H bond of 8-aminoquinoline amides has been developed. This method employed low-cost and innoxious sodium halides as halogenation reagents and oxone as an oxidant. The

Highly regioselective and stereoselective synthesis of C-Aryl glycosidesvianickel-catalyzedortho-C-H glycosylation of 8-aminoquinoline benzamides

Chen, Xi,Ding, Ya-Nan,Gou, Xue-Ya,Liang, Yong-Min,Luan, Yu-Yong,Niu, Zhi-Jie,Shi, Wei-Yu,Zhang, Zhe,Zheng, Nian

, p. 8945 - 8948 (2021/09/10)

C-Aryl glycosides are of high value as drug candidates. Here a novel and cost-effective nickel catalyzedortho-CAr-H glycosylation reaction with high regioselectivity and excellent α-selectivity is described. This method shows great functional group compatibility with various glycosides, showing its synthetic potential. Mechanistic studies indicate that C-H activation could be the rate-determining step.

Visible-Light-Triggered Decarboxylative Alkylation of 8-Acylaminoquinoline with N -Hydroxyphthalimide Ester

Aisha, Aertuke,Jin, Can,Li, Deyu,Sun, Bin,Zhu, Rui,Zhuang, Xiaohui

supporting information, p. 677 - 682 (2020/04/08)

A facile protocol for visible-light-induced decarboxylative radical coupling of NHP esters with 8-aminoquinoline amides is reported, affording a highly efficient approach to synthesize a variety of 2-alkylated or 2,4-dialkylated 8-aminoquinoline derivativ
