17684-75-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17684-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,8 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17684-75:
(7*1)+(6*7)+(5*6)+(4*8)+(3*4)+(2*7)+(1*5)=142
142 % 10 = 2
So 17684-75-2 is a valid CAS Registry Number.

Structural Fluxionality in the Tricyclo2,8>nona-3,6-dienyl and Bicyclonona-2,6,8-trienyl Radicals

Walton, John C.

, p. 2169 - 2176 (1989)

E.s.r observation of radicals derived from 9-bromtricyclo2,8>nona-3,6-diene, and related compounds, showed that they rearrange by β-scission to bicyclonona-2,6,8-trienyl radicals extremly rapidly; the latter radicals have hyperfine splittings similar to those of allyl radicals. 9-Deuterio- and 2-deuterio-9-bromotricyclo2,8>nona-3,6-diene were reduced with tributyltin hydride.The pattern of deuterium scrambling in the bicyclonona-2,6,8-triene and tricyclo2,8>nona-3,6-diene products showed that the intermediate radicals take part in a degenerate rearrangement sequence which makes them fully fluxional in three dimensions.The two radicals are in equilibrium at ca. 375 K, but the bicyclotrienyl species is more important by a factor of ca. 102.Neither the experimental results nor MNDO semiempirical calculations provided any evidence of additional thermodynamic stabilisation in the radical pair beyond that expected for allyl delocalisation.

Novel Two-Step Synthesis of Homobarrelenones, Bicyclonona-3,6,8-trien-2-ones, from Tropones and 2,3-Bis(methoxycarbonyl)-7-oxabicyclohepta-diene by High-Pressure Cycloaddition-Thermal Cyclorevision Procedure

Tian, Guan Rong,Sugiyama, Shigeru,Mori, Akira,Takeshita, Hitoshi

, p. 1557 - 1560 (2007/10/02)

The Diels-Alder adduct of tropone with 2,3-bis(methoxycarbonyl)-7-oxabicyclohepta-2,5-diene formed homobarrelenone by heating at ca. 130 deg C.Similarly prepared were 1-hydroxy-, 3-methoxy-, 1-chloro-, and 3-chlorohomobarrelenones.High-pressure cycloaddition improved the yields of the Diels-Alder adducts.
