126215-93-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126215-93-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,2,1 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126215-93:
(8*1)+(7*2)+(6*6)+(5*2)+(4*1)+(3*5)+(2*9)+(1*3)=108
108 % 10 = 8
So 126215-93-8 is a valid CAS Registry Number.

Synthesis of annulated pyridines by intramolecular inverse-electron-demand hetero-diels-alder reaction under superheated continuous flow conditions

Martin, Rainer E.,Morawitz, Falk,Kuratli, Christoph,Alker, Andre M.,Alanine, Alexander I.

supporting information; experimental part, p. 47 - 52 (2012/01/14)

Pyrimidine alkynes can be transformed into the corresponding annulated pyridines efficiently in flow. The superheating of organic solvents far beyond their boiling point enables toxic and difficult to workup solvents such as nitrobenzene or chlorobenzene,

The present invention provides compounds of formula I having BACE1 and/or BACE2 inhibitory activity, their manufacture, pharmaceutical compositions containing them and their use as therapeutically active substances. The active compounds of the present inv

INTRAMOLECULAR DIELS-ALDER REACTIONS OF 2-(ALKYNYL)PYRIMIDINES AND 2-(ALKYNYL)PYRIDINES

Frissen, A. E.,Marcelis, A. T. M.,Geurtsen, G.,Bie, D. A. de,Plas, H. C. van der

, p. 5151 - 5162 (2007/10/02)

Pyrimidines 3,7 and 13 carrying an ο-alkynyl side-chain -CR2(CH2)nCH2CCH (R=H, CN; n=1,2) at the 2-position undergo intramolecular inverse electron demand Diels-Alder reactions across the C-2 and C-5 positions.Loss of hydrogen cyanide, caused by a retro-Diels-Alder reaction, from the intermediate cycloadducts leads to annelated pyridines 5,9 and 15, respectively.Similarly, from the nitropyridines 16 the 2,3-dihydronitro-1H-indenes 18 are obtained.The influence of electronic and steric effects on the rate of cycloaddition is discussed.Gem-disubstitution on the chain connecting the reaction centers leads to a considerable rate enhancement for compounds 3 vs 13.Compounds 7, having an extra methylene group in the tether between diene and dienophile, react much slower than compounds 3 due to decreased entropic assistance.
