71540-66-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71540-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,4 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 71540-66:
(7*7)+(6*1)+(5*5)+(4*4)+(3*0)+(2*6)+(1*6)=114
114 % 10 = 4
So 71540-66-4 is a valid CAS Registry Number.

NITROGEN BRIDGEHEAD COMPOUNDS PART 16. FACILE TOTAL SYNTHESIS OF 7,8-DIHYDRO-13H-INDOLOPYRIDO-QUINAZOLIN-5-ONE (RUTECARPINE).

Koekoesi, Jozsef,Hermecz, Istvan,Szasz, Gyoergy,Meszaros, Zoltan

, p. 4861 - 4862 (1981)

Rutecarpine 1 has been synthetised from hydrazone 2 in high yield by Fischer indole synthesis.Hydrazone 2 has been prepared from 3 with benzenediazonium chloride or 5 with phenylhydrazine. 2 Shows a solvent dependent E-Z isomerism.

, p. 200 - 206 (2007/10/02)

The quinazoline bases pentamethylenequinazoline and peganol react with bromosuccinimide in glacial acetic acid to form the corresponding 6-bromoquinazoline derivatives.Some by-products of the bromination reaction have been isolated and characterized. 6-Bromopeganol has been subjected to x-ray structural analysis.

Nitrogen Bridgehead Compounds. Part 45. Synthesis of 6-Arylhydrazono-6,7,8,9-tetrahydro-11H-pyridoquinazolin-11-ones

Koekoesi, Jozsef,Hermecz, Istvan,Podanyi, Benjamin,Szasz, Gyoergy,Meszaros, Zoltan

, p. 1301 - 1306 (2007/10/02)

A series of 6-arylhydrazono-6,7,8,9-tetrahydro-11H-pyridoquinazolin-11-ones 3-37, convenient starting materials for indolopyridoquinazolines, were prepared by diazonium coupling between aryldiazonium chlorides and 6,7,8,9-tetrahydro- 2, 6-formyl-6,7,8,9-tetrahydro- 39, 6-(dimethylamino)methylene-6,7,8,9- 38 or 6-carboxyl-6,7,8,9-tetrahydro-11H-pyridoquinazolin-11-ones 43.The arylhydrazono derivatives were also prepared from 6-bromo- 45 or 6,6-dibromo-6,7,8,9-tetrahydro-11H-pyridoquinazolines 46 with arylhydrazines.The structures of the 6-arylhydrazonopyridoquinazolines were characterized by uv and 1H nmr spectroscopy.The 6-arylhydrazono derivatives show a solvent-dependent E-Z isomerism.
