106334-36-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 106334-36-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,3,3 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 106334-36:
(8*1)+(7*0)+(6*6)+(5*3)+(4*3)+(3*4)+(2*3)+(1*6)=95
95 % 10 = 5
So 106334-36-5 is a valid CAS Registry Number.

UNSYMMETRICAL CONNECTIVE OLEFINATION BY KORNBLUM NITRO-SYNTHESIS : APPLICATIONS IN PHYTUBERIN CHEMISTRY

Crombie, Leslie,Roughley, Brian S.

, p. 3147 - 3156 (2007/10/02)

Kornblum unsymmetrical olefin synthesis employing radical-anion chain crossed-coupling (light catalysed) of a mono- and a gem-di-nitro-compound, followed by reductive NO2 removal, is examined in the context of a hindered olefin structure required for phytuberin synthesis.Whilst successful for a tetrasubstituted olefin model (for which a Witting approach failed), increasing substitution on the β-position of the mono-nitro component supressed the coupling reaction, presumably for steric reasons.An alternative coupling involving a bromonitrocyclohexane and a mononitroacetal caused symmetrical coupling of the mononitro-component in high yield, rather than a crossed reaction.Reductive elimination (using Na2S/DMF) from either rac.- or meso- 1,2-dinitro-1,2-diphenylethane leads to (E)-stilbene 98percent (E) > probably through a stabilised radical or anion.A convenient preparation of triphenylisoxazoline-N-oxide is reported.
