Check Digit Verification of cas no

The CAS Registry Mumber 1225462-92-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,5,4,6 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1225462-92:
(9*1)+(8*2)+(7*2)+(6*5)+(5*4)+(4*6)+(3*2)+(2*9)+(1*2)=139
139 % 10 = 9
So 1225462-92-9 is a valid CAS Registry Number.

2-(1-Methylhydrazinyl)pyridine as a reductively removable directing group in a cobalt-catalyzed C(sp2)-H bond alkenylation/annulation cascade

Zhai, Shengxian,Qiu, Shuxian,Chen, Xiaoming,Wu, Jiang,Zhao, Hua,Tao, Cheng,Li, Yun,Cheng, Bin,Wang, Huifei,Zhai, Hongbin

, p. 98 - 101 (2017)

We describe a new application of 2-(1-methylhydrazinyl)pyridine as a bidentate directing group to directing cobalt-catalyzed C(sp2)-H alkenylation/annulation of the corresponding benzoic hydrazides to form an isoquinoline backbone, via reacting

Synthesis of isoquinolone via rhodium(III)-catalyzed C-H activation with 1,4,2-dioxazol-5-ones as oxidizing directing group

Zhu, Huajian,Zhuang, Rangxiao,Zheng, Wenya,Fu, Liping,Zhao, Yuanke,Tu, Luping,Chai, Yitao,Zeng, Linghui,Zhang, Chong,Zhang, Jiankang

, p. 3108 - 3112 (2019/05/08)

An efficient rhodium-catalyzed direct C-H activation for the synthesis of isoquinolone with 1,4,2-dioxazol-5-ones as oxidizing directing groups have been developed, which featured mild reaction conditions, short reaction time and satisfactory yield.

Direct access to cobaltacycles via C-H activation: N-chloroamide- enabled room-temperature synthesis of heterocycles

Yu, Xiaolong,Chen, Kehao,Guo, Shan,Shi, Pengfei,Song, Chao,Zhu, Jin

supporting information, p. 5348 - 5351 (2017/11/07)

Cobaltacycle synthesis via C-H activation has been achieved for the first time, providing key mechanistic insight into cobalt catalytic chemistry. NChloroamides are used as a directing synthon for cobalt-catalyzed roomtemperature C-H activation and construction of heterocycles. Alkynes as coupling partners allow convenient access to isoquinolones, a class of synthetically and pharmaceutically important compounds. The broad substrate scope enables a diverse range of substitution patterns to be incorporated into the heterocyclic scaffold.
