77669-79-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77669-79-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,6 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77669-79:
(7*7)+(6*7)+(5*6)+(4*6)+(3*9)+(2*7)+(1*9)=195
195 % 10 = 5
So 77669-79-5 is a valid CAS Registry Number.

BENZINDENE AND ITS KATZ REACTION

Burger, Ulrich,Thorel, Pierre-Jean,Schaller, Jean-Pierre

, p. 3155 - 3156 (2007/10/02)

A novel and very short synthesis of the useful title hydrocarbon 2 is presented.Its key step is based on a Diels-Alder reaction of isobenzofuran 4.The lithium salt of 2 gives a remarkably stable valence isomer of anthracene 1 in a reaction analogous to the indene -> benzobenzvalene transformation.

SYM-BENZVALENO-BENZO-BENZVALENE, A DOUBLE VALENCE ISOMER OF ANTHRACENE

Gandillon, Gerard,Bianco, Bernard,Burger, Ulrich

, p. 51 - 54 (2007/10/02)

Dilithio-s-indacene (1) on reaction with excess chlorocarbene produces s-benzvaleno-benzo-benzvalene (3).Unlike benzvalene, it does not aromatize on heating but decomposes stepwise to 1,5- and 1,7-bis-methylene-dihydro-indacene (6 and 7).
