Check Digit Verification of cas no
The CAS Registry Mumber 84604-92-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,0 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84604-92:
(7*8)+(6*4)+(5*6)+(4*0)+(3*4)+(2*9)+(1*2)=142
142 % 10 = 2
So 84604-92-2 is a valid CAS Registry Number.

Synthesis of 9,10-dihydrosilaanthracenes with substituents ortho to the silicon and methylene bridges
Bedard, Thomas C.,Corey, Joyce Y.,Lange, Lura D.,Rath, Nigam P.
, p. 261 - 272 (2007/10/02)
The generation of 9,10-dihydrosilaanthracenes with substituents on benzo ring carbons, specifically in the 4,5-positions adjacent to the methylene bridge, has been developed.Attempts to prepare the 1,8-isomer where the substituents are adjacent to the silicon bridge are also described.The diarylmethane precursors to the substituted 9,10-dihydrosilaanthracenes required the synthesis of 2,3-dihalotoluenes as well as isomeric 2,6-disubstituted benzaldehydes which were then condensed to diarylmethanols through the Grignard reagents.Ring closure to the 4,5-dimethyl-9,9-dialkyl-9,10-dihydro-9-silaanthracene, I, required the use of Rieke magnesium.The structure of I (alkyl = iPr) was determined and demonstrates that the introduction of substituents adjacent to the methylene bridge causes the dihydrosilaanthracene framework to become nearly planar with a dihedral (or butterfly) angle of 170 deg C.
