5202-73-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5202-73-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5202-73:
(6*5)+(5*2)+(4*0)+(3*2)+(2*7)+(1*3)=63
63 % 10 = 3
So 5202-73-3 is a valid CAS Registry Number.

Effect of micellar medium on photoannelation vs energy transfer in the system excited cyclohex-2-en-1-one-cyclopentadiene

Kumar, M. Suresh,Rao, Jampani Madhusudana

, p. 5383 - 5388 (2007/10/02)

The relative ratio of enone-CPD adducts and C15H18 formed in the photochemical reaction between cyclohex-2-en-1-one and its 4,4 dimethyl derivative and CPD in different media suggest that an exciplex is responsible for 2+2 photoannelation and energy transfer and a transoid or twisted enone for photo Diels-Alder reaction.

anti--Dicyclopentadiene

Grimme, Wolfram,Schumachers, Lothar,Roth, Wolfgang R.,Breuckmann, Rolf

, p. 3197 - 3208 (2007/10/02)

The synthesis of anti-tricyclo2,5>deca-3,7-diene (2) starting from the -cycloadduct 4a derived from cyclopentadiene and tropon is described.Compound 2 decomposes at 200 deg C yielding a mixture of cyclopentadiene (12), endo--dicyclopentadiene (13), anti-cis--dicyclopentadiene (14) and the cyclopentenyl-cyclopentadienes 15 and 16.The formation of a common diradical intermediate 11 in the decomposition of 2, 13 and 14 has been sought by means of the kinetic analyses of these reactions.
