γ-Lactone de l'acide (chloro-2hydroxy-3cyclohexenyl-4)acetique-cis is a complex organic chemical compound with the molecular formula C7H9ClO3. It is a γ-lactone derivative, which is a cyclic ester formed from the intramolecular esterification of a hydroxy acid. This specific compound features a chlorinated cyclohexenyl ring with a cis configuration, indicating that the hydroxyl group and the chlorine atom are on the same side of the double bond. It is synthesized from the corresponding hydroxy acid through a cyclization reaction, and it may have potential applications in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 78002-59-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,0 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78002-59:
(7*7)+(6*8)+(5*0)+(4*0)+(3*2)+(2*5)+(1*9)=122
122 % 10 = 2
So 78002-59-2 is a valid CAS Registry Number.

Ouverture de dichlorocyclopropanes en presence d'un nucleophile interne. Absence de participation intramoleculaire. Rearrangement concerte en chlorures allyliques

Chiche, Laurent,Christol, Henri,Coste, Jacques,Pietrasanta, Francine,Plenat, Francoise

, p. 164 - 174 (2007/10/02)

It is shown that a conveniently placed internal nucleophile (carboxyl group) is not involved with the rearrangement of a diclorocyclopropane into an allylic chloride.This result appears to support a concerted mechanism of a ?s2 + ?a2 type for this rearrangement.In the products obtained, the allylic chloride may undergo displacement either by solvent (H2O), leading to alcohols, or by the internal carboxyl group, leading to a lactone.
