Check Digit Verification of cas no

The CAS Registry Mumber 1303507-75-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,3,5,0 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1303507-75:
(9*1)+(8*3)+(7*0)+(6*3)+(5*5)+(4*0)+(3*7)+(2*7)+(1*5)=116
116 % 10 = 6
So 1303507-75-6 is a valid CAS Registry Number.

Direct N- sec -Alkylation of Amides by Reaction of α-Halohydroxamates and Sulfonylindoles: An Approach to 3-Indolyl Methanamines

Chen, Yuan,Guo, Xiaoqiang,Zhou, Chuang,Chen, Lianmei,Kang, Tairan

, p. 851 - 856 (2019)

A catalyst-free, base-mediated N- sec -alkylation of amides by reaction of sulfonylindoles and α-halohydroxamates has been developed. The N- sec -alkylation of amides reaction is based on an intermolecular nucleophilic addition of vinylogous imine with N

Synthesis of 2-Aminoimidazolones and Imidazolones by (3 + 2) Annulation of Azaoxyallyl Cations

DiPoto, Maria C.,Wu, Jimmy

, p. 499 - 501 (2018)

The first examples of (3 + 2) annulations between azaoxyallyl cations and cyanamides and nitriles to give the corresponding 2-aminoimidazolones and imidazolones are reported. On the basis of the isolation of unexpected imidate products with certain substr

Efficient one-pot synthesis of 1,3-dihydro-2H-pyrrol-2-one derivatives via aza-oxyallylic cations

Wang, Gangqiang,Chen, Rongxing,Wu, Minghu,Sun, Shaofa,Luo, Xing,Chen, Zhi,Guo, Haibing,Chong, Carlos,Xing, Yalan

, p. 847 - 850 (2017)

An efficient synthesis of functionalized 1,3-dihydro-2H-pyrrol-2-one was developed based on a [3+2] cycloaddition reaction of aza-oxyallylic cations and alkynes. With this novel method, a variety of substituted alkynes were readily converted into their co

[3 + 2]-Cycloaddition of Azaoxyallyl Cations with 1,2-Benzisoxazoles: A Rapid Entry to Oxazolines

Feng, Juan,Zhao, Ming,Lin, Xuanzi

, p. 9548 - 9560 (2019/08/26)

A novel and efficient [3 + 2] cycloaddition reaction of azaoxyallyl cations and 1,2-benzisoxazoles to give oxazoline derivatives has been developed. The transformation provides a rapid entry to functionalized oxazoline scaffolds under mild and transition-metal-free conditions, which will greatly expand the reaction types of heterocycle chemistry and pave the way for syntheses of bioactive compounds.

An efficient synthesis of oxazolines: Via a cascade reaction between azaoxyallyl cations and 1,2-benzisoxazoles

Sun, Li,Liu, Yi,Wang, Yankai,Li, Yuanyuan,Liu, Zhiwen,Lu, Tao,Li, Wenhai

supporting information, p. 7526 - 7530 (2019/08/20)

A formal [3 + 2] cycloaddition reaction between the C and O terminals of azaoxyallyl cations formed in situ and 1,2-benzisoxazoles has been realized. This one-pot cycloaddition method provided an effective and practical pathway to synthesize oxazoline in good yields under mild conditions. The title products exhibited unique fluorescence properties.
