Check Digit Verification of cas no
The CAS Registry Mumber 28736-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,3 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28736-47:
(7*2)+(6*8)+(5*7)+(4*3)+(3*6)+(2*4)+(1*7)=142
142 % 10 = 2
So 28736-47-2 is a valid CAS Registry Number.

Synthesis of 6,13-difluoropentacene
Tripp, Matthias W.,Koert, Ulrich
, p. 2136 - 2140 (2020)
6,13-Difluoropentacene was synthesized from 1,4-difluorobenzene. Friedel-Crafts annulation of the latter with phthalic anhydride and subsequent reduction of the anthraquinone gave 1,4-difluoroanthracene. After ortho-lithiation and reaction with phthalic anhydride a carboxylic acid was obtained whose Friedel-Crafts acylation and subsequent reductive removal of the oxygen-functionalities resulted in the formation of the target compound. The HOMO-LUMO gap of 6,13-difluoropentacene was determined via UV-vis spectroscopy and compared to other fluorinated pentacenes.
