99859-27-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99859-27-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,5 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99859-27:
(7*9)+(6*9)+(5*8)+(4*5)+(3*9)+(2*2)+(1*7)=215
215 % 10 = 5
So 99859-27-5 is a valid CAS Registry Number.

Electrochemical oxidative cyclization of: N -allylcarboxamides: Efficient synthesis of halogenated oxazolines

He, Yanyang,Liu, Chenwei,Wu, Xiao-Feng,Yin, Yanzhao,Yin, Zhiping

, p. 663 - 667 (2022/01/22)

Herein, we reported an efficient and sustainable intramolecular electrochemical cyclization of N-allylcarboxamides for the synthesis of various halogenated oxazolines. This method was conducted in a simple undivided cell by employing lithium halogen salts

CuBr2-promoted intramolecular bromocyclization of N-allylamides and aryl allyl ketone oximes

Yang, Chun-Hua,Xu, Zhong-Qi,Duan, Lili,Li, Yue-Ming

, p. 6747 - 6753 (2017/10/26)

A new and easy-to-perform route to 2-oxazolines amd isoxazolines was reported. Using CuBr2 as both the bromide source and the reaction promoter, bromocyclization of N-allylamides and allyl ketone oximes proceeded readily, leading to oxazolines
