Check Digit Verification of cas no

The CAS Registry Mumber 1310709-07-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,7,0 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1310709-07:
(9*1)+(8*3)+(7*1)+(6*0)+(5*7)+(4*0)+(3*9)+(2*0)+(1*7)=109
109 % 10 = 9
So 1310709-07-9 is a valid CAS Registry Number.

Synthesis of 2-substituted indoles by iridium (III)-catalyzed C–]H functionalization of N-phenylpyridin-2-amines

Zhang, Lei,Chen, Junyu,Chen, Jinkang,Jin, Licheng,Zheng, Xiangyun,Jiang, Xinpeng,Yu, Chuanming

, p. 1053 - 1056 (2019)

A highly regioselective synthesis of 2-substituted indoles was realized through Ir(III)-catalyzed C–]H functionalization of N-phenylpyridin-2-amines followed by the reaction with sulfoxonium ylides and intramolecular cyclization under mild conditions. The reaction completed with broad range of substrate scopes and gave various 2-substituted indoles in up to 98% yields.

Iridium(III)-Catalyzed Tandem Annulation of Pyridine-Substituted Anilines and α-Cl Ketones for Obtaining 2-Arylindoles

Cui, Xin-Feng,Qiao, Xin,Wang, He-Song,Huang, Guo-Sheng

, p. 13517 - 13528 (2020/12/15)

A facile and expeditious protocol for the synthesis of 2-arylindole compounds from readily available N-(2-pyridyl)anilines and commercially available α-Cl ketones through iridium-catalyzed C-H activation and cyclization is reported here. As a complementary approach to the conventional strategies for indole synthesis, the transformation exhibits powerful reactivity, tolerates a large number of functional groups, and proceeds with good to excellent yields under mild conditions, providing a straightforward method to obtain structurally diverse and valuable indole scaffolds. Furthermore, the reaction could be easily scaled up to gram scale.

Ruthenium-catalyzed synthesis of indole derivatives from: N -aryl-2-aminopyridines and alpha-carbonyl sulfoxonium ylides

Cui, Xin-Feng,Ban, Zi-Hui,Tian, Wa-Fa,Hu, Fang-Peng,Zhou, Xiao-Qiang,Ma, Hao-Jie,Zhan, Zhen-Zhen,Huang, Guo-Sheng

, p. 240 - 243 (2019/01/10)

Indole is a ubiquitous structural motif with important applications in many areas of chemistry. Given this, a simple and efficient Ru(ii)-catalyzed synthesis of indole via intermolecular annulation of N-aryl-2-aminopyridines and sulfoxonium ylides was proposed and accomplished. Excellent selectivity and good functional group tolerance of this transformation were observed. This protocol provides easy access to a wide variety of useful indoles in the presence of a commercially available [Ru(p-cymene)Cl2]2 catalyst. A possible mechanism for the reaction pathway was also proposed. More importantly, this reaction will offer a useful method for the construction of enantioenriched indole frameworks.
