Check Digit Verification of cas no

The CAS Registry Mumber 15914-94-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,1 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15914-94:
(7*1)+(6*5)+(5*9)+(4*1)+(3*4)+(2*9)+(1*4)=120
120 % 10 = 0
So 15914-94-0 is a valid CAS Registry Number.

Tetraols as templates for the synthesis of large endo-functionalized macrocycles

Stoltenberg, Dennis,Luethje, Sonja,Winkelmann, Ole,Naether, Christian,Luening, Ulrich

experimental part, p. 5845 - 5859 (2011/12/05)

Forty-six- and fifty-membered endo-functionalized macrocycles were obtained by template syntheses with new stiff tetracyclic tetraols 10 and 11. Reaction of dialkenylatedboronic acids 1 with template molecules 10 and 11 generated preorganized bisboronic esters 18 and 19, which were cyclized by ring-closing olefin metathesis. Resulting bimacrocycles 20 and 21 were obtained in ca. 60% yield when alkenyl chains of sufficient lengths were used. The E/E, E/Z, and Z/Z mixtures were hydrogenated to give saturated bimacrocycles 24 and 25 in excellent yields. The removal of the tetraol templates was possible by hydrolysis in the presence of dimethyl sulfate, which was needed to trap the liberated template. Thus, bis-endo-boronic acids 27e and 27f were obtained. The relative stereochemistry of the diastereoisomeric templates and the bimacrocyclic nature of the cyclization products were proven by X-ray structure analyses (for 12 and 26d).

Rearrangement and Cycloreversion of Diels-Alder Adducts of Cyclic 1,3-Dienes to Norbornadienes. A Novel homo-Cope Rearrangement. Evidence for Competitive Pericyclic and Diradical Processes

Hochstrate, Dirk,Klaerner, Frank-Gerrit

, p. 745 - 754 (2007/10/02)

On thermolysis of endo,endo-5, endo,endo-17, and endo,exo-17 ( the endo,endo and endo,exo Diels-Alder adducts of cyclopentadiene 7 or dimethylfulvene 15 to norbornadiene 8 or 7-isopropylidenenorbornadiene 20), a novel type of homo-Cope rearrangement leading to 6, 21, and 23a, respectively, competes with the retro-Diels-Alder reactions.According to a force-field analysis of the kinetic parameters, the competitive reactions (rearrangement and retro-Diels-Alder reaction) of endo,endo-5 occur in a pericyclic fashion whereas in the isopropylidene-substituted systems stepwise processes compete with the corresponding pericyclic reactions.Indirect experimental evidence for this assumption comes from a stereochemical analysis of the retro-Diels-Alder reaction in the cis-5,6-dideuterionorbornene derivatives exo-36-d2, endo-36-d2 and exo-39-d2, endo-39-d2 occuring stereospecifically in the case of exo-36-d2, endo-36-d2 and non-stereospecifically in the case of exo-39-d2, endo-39-d2.The change in mechanism rationalized by a different (allyl vs. pentadienyl) stabilization of the potential diradical intermediates in the stepwise reactions. - Key Words: Kinetic parameters / Stepwise and pericyclic reactions / Calculations, force field / Calculations of transition-state resonance energy (energy of concert)
