6553-48-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6553-48-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,5 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6553-48:
(6*6)+(5*5)+(4*5)+(3*3)+(2*4)+(1*8)=106
106 % 10 = 6
So 6553-48-6 is a valid CAS Registry Number.

Evidence for pericyclic and stepwise processes in the cyclodimerization of chloroprene and 1,3-butadiene from pressure dependence and stereochemistry. Experimental and theoretical volumes of activation and reaction

Kl?rner, Frank-Gerrit,Krawczyk, Bernd,Ruster, Volker,Deiters, Ulrich K.

, p. 7646 - 7657 (2007/10/02)

From the pressure dependence of cyclodimerization of chloroprene, it has been concluded that volumes of activation may be useful for the distinction between competing concerted and stepwise cycloadditions. Accordingly, one of the [4 + 2] cyclodimers, 1,4-

Small Rings. Part 32. The Gas Phase Kinetics, Mechanism, and Energy Hypersurface for the Thermolyses of syn- and anti-Tricyclo2,5>-octane

Walsh, Robin,Martin, Hans-Dieter,Kunze, Michael,Oftring, Alfred,Beckhaus, Hans-Dieter

, p. 1076 - 1083 (2007/10/02)

The title reactions have been studied at low pressure (1-10 Torr) and in the temperature ranges 390-419 2,5/octane(syn-TCO)> and 412-445 K (anti-TCO).The major products from both compounds were cis,cis and cis,trans-cyclo-o

Diene Oligomerization. XV. Palladiumcomplexcatalyzed Telomerization of Butadiene with Amines and Dimerization in the Presence of Ketoximes

Beger, J.,Meier, F.

, p. 69 - 80 (2007/10/02)

Butadiene reacts with primary or secondary amines and with the homogeneous catalytic system bis-acetylacetonatopalladium-(II)/triphenylphosphine to form 1-amino-octa-2,7-dienes.The rate and the selectivity of the reaction increase in presence of cocatalysts as triarylphosphates instead of triphenylphosphine and if the reaction proceeds in a protic media - in alcohols, water or lower carboxylic acids.A number of 1-aminoocta-2,7-dienes were prepared.If oximes act as organic nitrogen compounds, only n-octa-1,3,7-triene is selectively formed.Schiff' bases aldolisate under the conditions of the reaction.
