Check Digit Verification of cas no

The CAS Registry Mumber 819793-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,9,7,9 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 819793-90:
(8*8)+(7*1)+(6*9)+(5*7)+(4*9)+(3*3)+(2*9)+(1*0)=223
223 % 10 = 3
So 819793-90-3 is a valid CAS Registry Number.

2-(2-Benzoylethynyl)-5-phenylpyrrole: Fixation of cis- and trans-rotamers in a crystal state

Trofimov, Boris A.,Stepanova, Zinaida V.,Sobenina, Lubov N.,Mikhaleva, Albina I.,Sinegovskaya, Lidia M.,Potekhin, Konstantin A.,Fedyanin, Ivan V.

, p. 229 - 232 (2005)

2-(2-Benzoylethynyl)-5-phenylpyrrole forms two crystal modifications with the carbonyl group oriented in cis- and trans-positions relative to the nitrogen atom thus representing the first example of the solid state stable rotamers around the C≡C bond system.

Reactions of 2-phenylpyrrole with bromobenzoylacetylene on metal oxides active surfaces

Trofimov, Boris A.,Sobenina, Lyubov' N.,Stepanova, Zinaida V.,Vakul'skaya, Tamara I.,Kazheva, Ol'ga N.,Aleksandrov, Grigorii G.,Dyachenko, Oleg A.,Mikhaleva, Al'bina I.

, p. 5541 - 5544 (2008/09/21)

The solvent-free interaction of 2-phenylpyrrole with bromobenzoylacetylene (room temperature) upon their grinding with solid metal oxides (MgO, CaO, ZnO, BaO, Al2O3, TiO2, ZrO2) and salts (CaCO3, ZrSi

Synthesis of 2-benzoylethynylpyrroles by cross coupling of 2-arylpyrroles with 1-benzoyl-2-bromoacetylene over aluminum oxide

Trofimov,Sobenina,Stepanova,Demenev,Mikhaleva,Ushakov,Vakul'skaya,Petrova

, p. 1348 - 1355 (2007/10/03)

Cross coupling of 2-arylpyrrole with benzoylbromoacetylene over aluminum oxide at room temperature gave 45-94% of 2-(benzoylethynyl)-5-arylpyrroles. Intermediate 2-(2-benzoyl-1-bromoethenyl)-5-arylpyrroles were isolated in up to 19% yield. The reaction wa

Silica-assisted reactions of pyrroles with 1-acyl-2-bromoacetylenes

Stepanova, Zinaida V.,Sobenina, Lubov' N.,Mikhaleva, Al'Bina I.,Ushakov, Igor' A.,Chipanina, Nina N.,Elokhina, Valentina N.,Voronov, Vladimir K.,Trofimov, Boris A.

, p. 2736 - 2742 (2007/10/03)

Pyrroles react with 1-acyl-2-bromoacetylenes at room temperature on silica to give 2-acyl-1,1-di(pyrrol-2-yl)ethenes as major products in yields of up to 60%. Under reaction conditions employed, the intermediates (E)-2-(2-acyl-1- bromoethenyl)pyrroles (3-
