Check Digit Verification of cas no
The CAS Registry Mumber 129815-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,1 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129815-97:
(8*1)+(7*2)+(6*9)+(5*8)+(4*1)+(3*5)+(2*9)+(1*7)=160
160 % 10 = 0
So 129815-97-0 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.
