943913-77-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 943913-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,9,1 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 943913-77:
(8*9)+(7*4)+(6*3)+(5*9)+(4*1)+(3*3)+(2*7)+(1*7)=197
197 % 10 = 7
So 943913-77-7 is a valid CAS Registry Number.

Copper(I)-Catalyzed Intramolecular N-N Coupling of Cyclopropyl O-Acyl Ketoximes: Synthesis of Spiro-fused Pyrazolin-5-ones

Zhang, Zhiguo,Li, Junlong,Huang, Guoqing,Sun, Kai,Zhang, Guisheng,Ma, Nana,Liu, Qingfeng,Liu, Tongxin

, p. 1309 - 1320 (2016/12/27)

A convenient copper-catalyzed approach has been developed for the synthesis of substituted spiro-fused pyrazolin-5-ones from readily available cyclopropyl O-acyl ketoximes via an intramolecular N N bond formation reaction. These catalytic reactions proceed in excellent yields with a broad scope.

Ag-containing all-carbon 1,3-dipoles: Generation and formal cycloaddition for furo[3,2-b]-β/γ-lactams

Zhang, Zhiguo,Zhang, Qian,Ni, Zhikun,Liu, Qun

supporting information; experimental part, p. 1269 - 1271 (2010/07/05)

A new strategy for highly diastereoselective synthesis of furo[3,2-b]-β-lactams and furo[3,2-b]-γ-lactams via a novel Ag(i)-mediated intramolecular 1,3-dipolar cycloaddition of oxo-N- propargylamides, is developed and the possible mechanism of these trans
