Check Digit Verification of cas no

The CAS Registry Mumber 432-24-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 432-24:
(5*4)+(4*3)+(3*2)+(2*2)+(1*4)=46
46 % 10 = 6
So 432-24-6 is a valid CAS Registry Number.

Method for preparing cyclocitral by micro-structural reactors

-

, (2017/02/09)

The invention discloses a method for preparing cyclocitral by micro-structural reactors. The method comprises steps as follows: a liquid raw material citral and organic amine in a mole ratio being 1: (0.8-1.5) are simultaneously pumped into a tubular reactor or one micro-structural reactor for an amination reaction, the reaction temperature of the reactor is controlled in a range of 10-20 DEG C, a flow velocity of a reaction liquid is controlled, the reaction liquid is enabled to totally stay in the reactor for 0.1-25 min, and obtained aldimine and concentrated sulfuric acid are injected into another micro-structural reactor and subjected to a ring closing reaction; a reaction product is neutralized by a sodium hydroxide solution and is subjected to acidic hydrolysis, liquid separation, reduced pressure distillation and drying, and a pale yellow oily product, namely, cyclocitral, is obtained. According to the method, the reaction time is short, the reaction temperature is accurate and controllable, and product selectivity and yield are high. The method adopts simple steps, and is convenient to operate and high in practicability.

Synthesis of three putative kairomones of the beech leaf-mining weevil Orchestes fagi (L.)

Mayo,Silk,Abeysekera,MaGee

supporting information, p. 1124 - 1132 (2016/07/21)

The beech leaf-mining weevil, Orchestes fagi (L.), also known as the beech flea weevil, is a common and widespread pest of beech, Fagus sylvatica L., in its native Europe. It now appears to be well established in Nova Scotia, Canada. We report a novel synthesis of 9-geranyl-p-cymene and syntheses of 9-geranyl-α-terpinene and 1,1-dimethyl-3-methylene-2-vinylcyclohexane, making partial use of known methods. All three of these compounds are found in beech leaf volatiles and/or wood and are putative kairomones of the beech leaf-mining weevil.

Nitriles and carbonyl groups as acceptors in titanocene-catalyzed radical cyclizations

Gansaeuer, Andreas,Piestert, Frederik,Huth, Inga,Lauterbach, Thorsten

scheme or table, p. 3509 - 3515 (2009/05/26)

A catalytic approach to the titanocene-mediated radical cyclization of epoxy nitriles and epoxy carbonyl compounds to hydroxy ketones and diols is described. The reaction is sensitive to the substitution pattern of the catalyst and especially useful for the preparation of cyclobutanones. It can also be used for nitrile group transfer.

Improved synthesis of methyl 3-oxo-2,6,6-trimethylcyclohex-1-ene-1- carboxylate, an A-ring intermediate for (±)strigol

Qianchao,Shiqing, Pi,Xinzhi, Chen

, p. 494 - 496 (2008/09/21)

Methyl 3-oxo-2,6,6-trimethylcyclohex-1-ene-1-carboxylate was synthesised over eight steps from the starting material of citral instead of α-ionone. KMnO4, HC(OEt)3 and O2/TEMPO/CuCl were substituted for NaIO4, CH3I and pyridinium chlorochromate, respectively. Every step was simplified and gave a 48% overall yield. The procedure is suitable for large scale production.

A novel unusual 17-carbon diterpenoid, named (+)-7-deoxynimbidiol, was isolated from the stalks of Celastrus hypoleucus (Oliv.) Warb. Its racemate and derivatives were synthesized, and the inhibitory activities of these compounds against four cultured human-tumor cell lines were evaluated. The structure-activity relationship was discussed.

Epoxy-pyronene: Obtention of cyclocitrals from ionones and precursor of new terpenic compounds

Marc,Soulet,Serramedan,Delmond

, p. 3381 - 3388 (2007/10/02)

The selective obtention of epoxy-pyronene from δ-pyronene has been realized using metachloroperbenzoic acid. The isomerization of this epoxidic compound with Lewis and protonic acids and on active alumina has been studied leading to cyclocitrals. Ionones are obtained from epoxy-pyronene by homologation with various C3 units, in the presence of paratoluenesulfonic acid in order to obtain β-cyclocitral in situ. New terpenic compounds with the cyclogeranyl skeleton were obtained from epoxy-pyronene by reduction followed by homologation.
