723-19-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 723-19-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 723-19:
(5*7)+(4*2)+(3*3)+(2*1)+(1*9)=63
63 % 10 = 3
So 723-19-3 is a valid CAS Registry Number.

Palladium-catalyzed cyclopropanation of electron-deficient olefins with aryldiazocarbonyl compounds

Chen, Shufeng,Ma, Jian,Wang, Jianbo

scheme or table, p. 6781 - 6783 (2009/04/11)

A concise and efficient protocol for the preparation of cyclopropanes from various aryldiazocarbonyl compounds and electron-deficient olefins catalyzed by Pd(OAc)2 is reported.

Synthesis, stereochemistry, and chiroptical spectra of cyclopropyl lactones and thionolactones

Milewska, Maria J.,Gdaniec, Maria,Polonski, Tadeusz

, p. 3169 - 3180 (2007/10/03)

Several optically active substituted 3-oxabicyclo[3.1.0]hexan-2-ones and their thiocarbonyl analogues were synthesized, and their circular dichroism spectra are reported. It was found that the n-π* Cotton effect sign is determined by the helicity of an inherently chiral chromophore formed by the lactone or thiolactone group and the cyclopropyl moiety. The π-π* Cotton effect of thiocarbonyl compounds shows opposite sign to that observed for the lowest energy transition. The crystal structures of two compounds were solved to establish their molecular geometries. Copyright (C) Elsevier Science Ltd.
