Check Digit Verification of cas no

The CAS Registry Mumber 81039-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,3 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81039-03:
(7*8)+(6*1)+(5*0)+(4*3)+(3*9)+(2*0)+(1*3)=104
104 % 10 = 4
So 81039-03-4 is a valid CAS Registry Number.

Selectfluor mediated one pot synthesis of cyclohexanone ring fused isoxazole derivatives

Rajawinslin,Raihan, Mustafa J.,Janreddy, Donala,Kavala, Veerababurao,Kuo, Chun-Wei,Kuo, Ting-Shen,Chen, Mei-Ling,He, Chiu-Hui,Yao, Ching-Fa

, p. 7505 - 7510 (2014)

A Selectfluor and base mediated protocol for the synthesis of cyclohexanone ring fused isoxazole derivatives from isoxazoline N-oxides has been successfully developed. This rapid, one-pot, two-step transformation is achieved in acetonitrile, through nitroso intermediate followed by hydration, defluorination and N-O coupling in the presence of triethylamine. The scope and mechanism of the protocol have been demonstrated.

Effective synthesis of novel dihydrobenzisoxazoles bearing the 2-aminothiazole moiety and evaluation of the antiproliferative activity of their acylated derivatives

Khlebnicova, Tatyana S.,Lakhvich, Fedor A.,Matous, Anton E.,Piven, Yuri A.,Scherbakov, Alexander M.,Shchegolev, Yuri Yu.,Sorokin, Danila V.,Yastrebova, Margarita A.,Zinovich, Veronica G.
