Check Digit Verification of cas no
The CAS Registry Mumber 42523-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,2 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42523-15:
(7*4)+(6*2)+(5*5)+(4*2)+(3*3)+(2*1)+(1*5)=89
89 % 10 = 9
So 42523-15-9 is a valid CAS Registry Number.

Decarboxylative C-H arylation of benzoic acids under radical conditions
Seo, Sangwon,Slater, Mark,Greaney, Michael F.
, p. 2650 - 2653 (2012/07/27)
A decarboxylative radical cyclization reaction has been developed for the synthesis of fluorenones. The reaction uses Ag(I)/K2S 2O8 to oxidatively decarboxylate an aroylbenzoic acid to an aryl radical, which undergoes cyclization to afford fluorenone products in good yield.
Palladium-catalyzed annulation of arynes by 2-halobenzaldehydes: Synthesis of fluoren-9-ones
Zhang, Xiaoxia,Larock, Richard C.
, p. 3973 - 3976 (2007/10/03)
(Chemical Equation Presented) Arynes, generated in situ from 2-(trimethylsilyl)aryl triflates and CsF, undergo annulation by o-haloarenecarboxaldehydes in the presence of a Pd catalyst, providing a useful new method for the synthesis of fluoren-9-ones in good yields.
