Check Digit Verification of cas no

The CAS Registry Mumber 636-82-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 636-82:
(5*6)+(4*3)+(3*6)+(2*8)+(1*2)=78
78 % 10 = 8
So 636-82-8 is a valid CAS Registry Number.

1-alkenylcalcium iodide: Synthesis and stability

Koehler, Mathias,Goerls, Helmar,Langer, Jens,Westerhausen, Matthias

, p. 5237 - 5239 (2014)

To enhance the scope of heavy calcium-based Grignard reagents, 1,2-dihydro-4-iodonaphthalene (1) was reduced with calcium in THF giving tetrakis(thf) (1,2-dihydronaphth-4-yl)calcium iodide (2). This derivative represents a 1-alkenylcalcium complex based on X-ray structure determination and NMR data. The stability of this compound is significantly reduced compared with the aromatic naphthylcalcium iodide. Complex diversity: The class of heavy Grignard reagents is extended by a 1-alkenylcalcium iodide. This tetrakis(thf) (1,2-dihydronaphth-4-yl)calcium iodide contains a 1-alkenyl moiety based on structural and NMR spectroscopic studies (see figure).

Macrolactam Synthesis via Ring-Closing Alkene-Alkene Cross-Coupling Reactions

Goh, Jeffrey,Loh, Teck-Peng,Maraswami, Manikantha

supporting information, p. 9724 - 9728 (2020/12/21)

Reported herein is a practical method for macrolactam synthesis via a Rh(III)-catalyzed ring closing alkene-alkene cross-coupling reaction. The reaction proceeded via a Rh-catalyzed alkenyl sp2 C-H activation process, which allows access to macrocyclic molecules of different ring sizes. Macrolactams containing a conjugated diene framework could be easily prepared in high chemoselectivities and Z,E stereoselectivities.

Synthetic method for 3-acetoxy-2-cyclohexenyl-1-one and derivatives thereof

-

Paragraph 0019; 0021; 0023, (2019/10/01)

The invention discloses a synthetic method for 3-acetoxy-2-cyclohexenyl-1-one and derivatives thereof. The synthetic method comprises the following steps: (1) reacting a substance as described in thespecification with nitromethane at 110 DEG C to obtain a product I as described in the specification, wherein R in the product I is H or CH3; (2) reacting the product I of the step (1) with sodium nitrite and acetic acid at 37 DEG C to obtain a product II as described in the specification; (3) reacting the product II of the step (2) with methanol and concentrated sulfuric acid at 88 DEG C to obtain a product III as described in the specification; and (4) weighing the product III of the step (3), potassium carbonate, palladium on activated carbon and t-butyl hydroperoxide, adding the weighed materials into dichloromethane, carrying out a reaction at 0 DEG C, and allowing temperature to naturally rise to room temperature so as to obtain a product IV, wherein R in the product IV is H or CH3.The synthetic method of the invention is simpler and more efficient, and has high total yield; the toxicity of reagents used in the preparation is smaller than the toxicity of m-methoxybenzoic acid, thionyl chloride and the like used in the prior art; and the method is low in cost, simple and convenient in separation and purification, applicable to large-scale preparation and capable of realizingindustrial mass production. The synthetic method is applicable as a general synthetic method for 3-acetoxy-2-cyclohexenyl-1-one and 4-substituted derivatives thereof.
