13901-74-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13901-74-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,0 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13901-74:
(7*1)+(6*3)+(5*9)+(4*0)+(3*1)+(2*7)+(1*4)=91
91 % 10 = 1
So 13901-74-1 is a valid CAS Registry Number.

IBX-Promoted Oxidative Cyclization of N-Hydroxyalkyl Enamines: A Metal-Free Approach toward 2,3-Disubstituted Pyrroles and Pyridines

Gao, Peng,Chen, Huai-Juan,Bai, Zi-Jing,Zhao, Mi-Na,Yang, Desuo,Wang, Juan,Wang, Ning,Du, Lele,Guan, Zheng-Hui

, p. 7939 - 7951 (2020/07/16)

An iodoxybenzoic acid-mediated selected oxidative cyclization of N-hydroxyalkyl enamines was developed. Through this strategy, a variety of 2,3-disubstituted pyrroles and pyridines were produced in good selectivity involving oxidation of alcohol, followed by condensation of aldehyde and α-C of enamines. Furthermore, this metal-free method has several advantages, including the use of environmentally friendly reagents, broad substrate scope, mild reaction conditions, and high efficiency.

Studies on cycloaddition reactions of 1,3-diphenyl-2-azaallyl lithium and ethyl (benzylideneamino) acetate anion with α-oxoketene dithioacetals

Balu, Maliakel P.,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar

, p. 6771 - 6782 (2007/10/02)

The α-oxoketene dithioacetals undergo anionic [1,3] cycloaddition with 1,3-diphenyl-2-azaallyllithium to give either pyrroles or spiropyrrolines with two exceptions. Lithium bromide/triethylamine induced cycloaddition of ethyl (benzylideneamino)acetate (7
