Check Digit Verification of cas no

The CAS Registry Mumber 96972-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,9,7 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 96972-18:
(7*9)+(6*6)+(5*9)+(4*7)+(3*2)+(2*1)+(1*8)=188
188 % 10 = 8
So 96972-18-8 is a valid CAS Registry Number.

Cycloaddition of thiophene S-oxides to allenes, alkynes and to benzyne

Thiemann, Thies,Fujii, Hideki,Ohira, Daisuke,Arima, Kazuya,Li, Yuanqiang,Mataka, Shuntaro

, p. 1377 - 1384 (2007/10/03)

Thiophenes have been treated with alkynes in the presence of m-chloroperoxybenzoic acid to give substituted arenes as cycloadducts. Alternatively, thiophene S-oxides have been prepared by oxidation from thiophenes and have been subjected to cycloaddition with alkynes in a subsequent step. The outcome of the reaction is dependent on the steric demand of the thiophene S-oxide. Some thiophene S-oxides can be reacted at temperatures as high as 140°C without decomposition. Thiophenes as deoxygenated products are the main by-products. Reactions of thiophene S-oxides with allenes give in part thiabicyclo[2.2.1]heptene S-oxides of type 12a and 13 along with aromatized products. Thiophene S-oxides also cycloadd to benzyne.

Synthesis of stable 7-phosphanorbornadiene P-oxides

Matsumoto, Kiyoshi,Hashimoto, Shiro

, p. 201 - 203 (2007/10/02)

Nonbenzo-annelated stable 7-phosphanorbornadiene P-oxides have been prepared for the first time by the high pressure Diels-Alder reaction of 1,2,3,4,5-pentaphenylphosphole oxide with diaroylacetylenes.The P-oxides decompose around 100 deg C to give the 1,

Chemilumineszenz- und Oxidationsreactionen von Phthaloylperoxid und verwandten Verbindungen.

Gundermann, Karl-Dietrich,Steinfatt, Manfred,Witt, Peter,Paetz, Christian,Poeppel, Karl-Ludwig

, p. 2801 - 2822 (2007/10/02)

Phthaloylperoxid (PPO) und 4,5-Dichlorphthaloylperoxid ergeben mit fluoreszenzfaehigen aromatischen Kohlenwasserstoffen wie 9,10-Diphenylanthracen (DPA), 9,10-Bis(phenylethinyl)anthracen, Pyren, Perylen, aber auch heterocyclischen Verbindungen wie 1,3-Diphenylbenzofuran (9), Luminol oder Fluorescein Chemilumineszenz, die Quantenausbeuten bis 1E-3 Einstein/mol erreichen kann, wenn Phthalsaeureester als Loesungsmittel eingesetzt werden.Die Chemilumineszenz wird durch Sauerstoff hinsichtlich der Maximalintensitaet gesteigert, hinsichtlich der Lichtausbeute auf etwa 80percent verringert.Da bei Derivaten des 1,3-Diphenyl-benzofurans sowohl Chemilumineszenz, als auch Bildung der entsprechenden "Photooxdationsprodukte" (bei 9: o-Dibenzoylbenzol) beobachtet wurde, wird die Moeglichkeit der Bildung von Singulett-Sauerstoff aus PPO diskutiert.Die Bildung von Phthalsaeure-halbestern aus PPO und Olefinen anstelle des Auftretens von Hydroperoxiden wird ueber die thermodynamisch moegliche intermediaere Bildung von Benzocyclobutendion erklaert und ist kein grundsaetzlicher Widerspruch gegen das Auftreten von Singulett-Sauerstoff bei PPO-Reaktionen.
