124643-39-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124643-39-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,4 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 124643-39:
(8*1)+(7*2)+(6*4)+(5*6)+(4*4)+(3*3)+(2*3)+(1*9)=116
116 % 10 = 6
So 124643-39-6 is a valid CAS Registry Number.

Metal-free cascade boron–heteroatom addition and alkylation with diazo compounds

Lv, Jiahang,Zhao, Binlin,Han, Ying,Yuan, Yu,Shi, Zhuangzhi

, p. 691 - 694 (2020/07/13)

Transition metal-catalyzed carbene transfer reaction is one of the most notable advances for C?C bond formation reactionsduring the past decade, which has been widely employed in the preparation of C3-substituted indoles. Here, we described an efficient e

Nickel-catalyzed cyclization of 1,7-enynes for the selective synthesis of dihydrocyclobuta[c]quinolin-3-ones and benzo[b]azocin-2-ones

Cai, Yun,Chen, Fener,Hu, Yuanyuan,Jin, Hongwei,Li, Qiao,Liu, Yunkui,Zhou, Bingwei

supporting information, p. 11657 - 11660 (2021/11/12)

We herein described a nickel-catalyzed cyclization ofN-(o-ethynylaryl)acrylamides for the selective synthesis of dihydrocyclobuta[c]quinolin-3-ones and benzo[b]azocin-2-ones. The two varied products could be easily obtained by tuning the reaction temperature. This reaction features easy temperature-control, high efficiency, and gram-scale synthesis.

Copper-catalyzed trifluoromethylazidation and rearrangement of aniline-linked 1,7-enynes: Access to CF3-substituted azaspirocyclic dihydroquinolin-2-ones and furoindolines

Yu, Liu-Zhu,Wei, Yin,Shi, Min

supporting information, p. 8980 - 8983 (2017/08/15)

A set of reactions involving copper-catalyzed trifluoromethylazidation and then rearrangement of aniline-linked 1,7-enynes with the relatively poorly reactive Togni reagent I and TMSN3 was developed, and provided facile access to structurally d
