91859-82-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91859-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,5 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91859-82:
(7*9)+(6*1)+(5*8)+(4*5)+(3*9)+(2*8)+(1*2)=174
174 % 10 = 4
So 91859-82-4 is a valid CAS Registry Number.

Ozonide compounds with inhibitory activity for urokinase production and angiogenesis

-

, (2008/06/13)

The invention provides a urokinase production inhibitor or angiogenesis inhibitor comprising as an active component an ozonide derivative represented by the formula (1), and method of prevention or therapy using the inhibitor wherein A is an oxygen atom o

Ozonolyses of 1,2-Diphenyl- and 2-Phenylindene

Sugimoto, Toshiya,Teshima, Koichi,Nakamura, Norinaga,Nojima, Masatomo,Kusabayashi, Shigekazu,McCullough, Kevin J.

, p. 135 - 141 (2007/10/02)

Ozonolyses of 1,2-diphenylindene (7), 2-phenylindene (18), and the structurally related acyclic keto olefins 13, 14, 26, and 32 were conducted in MeOH/CH2Cl2 at -70 and 0 deg C.The structure of the indenes, 7 and 18, and the rection temperature, were foun

Stereochemical effects on the mechanism of the ozonolysis of (E)- and (Z)-o-(2-phenyl-3-methoxy-2-propenyl)benzophenone

McCullough, Kevin J.,Nakamura, Norinaga,Fujisaka, Tomohiro,Nojima, Masatomo,Kusubayasbi, Shigekazu

, p. 1786 - 1791 (2007/10/02)

The ozonolyses of (E)- and (Z)-o-(2-phenyl-3-methoxy-2-propenyl)benzophenone (6), which should proceed through a common carbonyl oxide intermediate 15, afforded distinctly different reaction product mixtures, suggesting that the substrate stereochemistry

Ozonolysis of Vinyl Ethers. Evidence for Intramolecular Oxygen Transfer from a Carbonyl Oxide Moiety to a Methoxyvinyl Group

Nakamura, Norinaga,Nojima, Masatomo,Kusabayashi, Shigekazu

, p. 4969 - 4973 (2007/10/02)

Ozonolysis of diene 1 in carbon tetrachloride gave exclusively the keto ester 2, while in methanol the keto olefin 17 was the major product.The behavior of model vinyl ethers 3a,b has revealed that a mechanism involving intramolecular oxygen atom transfer from the carbonyl oxide moiety to a methoxyvinyl group is the most probable for the keto ester formation from diene 1.

THE PHOTOCHEMICAL PREPARATION OF OZONIDES BY ELECTRON-TRANSFER PHOTO-OXYGENATION OF EPOXIDES

Schaap, A. Paul,Siddiqui, Shahabuddin,Prasad, Girija,Palomino, Eduardo,Sandison, Mark

, p. 2229 - 2236 (2007/10/02)

9,10-Dicyanoanthracene (DCA) sensitizes the electron-transfer photo-oxygenation of epoxides in oxygen-saturated acetonitrile to form ozonides.Epoxides with oxidation potentials lower than 2 V vs SCE quench the fluorescence of DCA and are converted to the
