Check Digit Verification of cas no

The CAS Registry Mumber 5023-60-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,2 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5023-60:
(6*5)+(5*0)+(4*2)+(3*3)+(2*6)+(1*0)=59
59 % 10 = 9
So 5023-60-9 is a valid CAS Registry Number.

Synthesis of benzyl thioether derivatives via N-heterocyclic carbene palladium(II)-catalyzed cross coupling of benzylammonium salts with thiophenols

Wang, Tao,Guo, Jiarui,Xu, Yongli,Wang, Xiaobo,Wang, Yan,Feng, Dandan,Liu, Lantao

, (2021/12/01)

A new route to benzyl thioether derivatives has been developed via the N-heterocyclic carbene palladium(II)-catalyzed cross coupling of benzylammonium salts with thiophenols. Under the optimal conditions, different benzylammonium salts could be well toler

, p. 301 - 310 (2020/09/07)

Twenty-four aryl benzyl sulfides, diaryl sulfides and dibenzyl sulfides were synthesized by four methods and characterized by 1H NMR, FT-IR and Gas chromatography. The reaction conditions of different synthesis methods were studied from the aspects of time, solvent, base and dispersant. The molecular structures of benzylphenyl sulfide (2S), (4-tert-butylbenzyl)(4-methylphenyl) sulfide (4S), (4-methylbenzyl)(4-methylphenyl) sulfide (9S), di(4-methylphenyl) sulfide (11S), (3,5-dimethylphenyl)(4-methyl phenyl) sulfide (15S), and dibenzyl sulfide (19S) [22] have been determined by single-crystal X-ray crystallography. Compounds 2S and 15S crystallize in the monoclinic space group P21/c, with a = 12.278(3), b = 15.894(3), c = 5.6056(11) ?, β = 94.532(2)°, and Z = 4 for 2S, and a = 9.800(9), b = 7.950(7), c = 16.690(15) ?, β = 100.890(12)°, and Z = 4 for 15S. The unit cell of 4S has a triclinic Pī symmetry with the cell parameters a = 6.0436(10), b = 8.7871(14), c = 15.535(2) ?, α = 81.921(2)°, β = 81.977(2)°, γ = 80.889(2)°, and Z = 2. Compounds 9S and 11S both crystallize in the orthorhombic space group P212121, with a = 6.188(3), b = 8.041(4), c = 26.005(14) ?, and Z = 4 for 9S, and a = 5.835(2), b = 8.010(3), c = 25.131(9) ?, and Z = 4 for 11S. Graphic Abstract: Twenty-four aryl sulfide compounds with different substituents were synthesized and characterized, and the molecular structures of six different sulfide compounds have been determined by single-crystal X-ray crystallography.[Figure not available: see fulltext.]

-

Paragraph 0056; 0057; 0058; 0059, (2021/04/03)

The invention belongs to the field of organic synthesis, and particularly relates to a photocatalytic synthesis method of aryl thioether and derivatives thereof. The synthesis method comprises the steps: dissolving an N-(sulfanyl) amide compound into a methyl aromatic compound under the protection of inert gas, and thus obtaining the aryl thioether compound under the action of light, a catalyst, aligand and alkali. According to the method, the coupling reaction of a C-S bond is completed through visible light induction by utilizing a light/Ni dual-catalytic system, so that the method has goodfunctional group compatibility, and the C-S bond compound can be selectively and efficiently constructed in one step. The method has the advantages of simple catalytic system, mild reaction conditions, economical, simple and easily available substrate, simple reaction operation and the like.
