Check Digit Verification of cas no

The CAS Registry Mumber 286-28-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 286-28:
(5*2)+(4*8)+(3*6)+(2*2)+(1*8)=72
72 % 10 = 2
So 286-28-2 is a valid CAS Registry Number.

LASER INDUCED SYNTHESYS: SELECTIVE FORMATION OF CYCLOHEXENE EPISULPHIDE FROM MOLECULAR SULPHUR S8

Bertaina, C.,Fellous, R.,Lemaire, F.,Stringat, R.

1,2-Epithiocyclohexane was obtained selectively by irradiation of a mixture of cyclohexene and sulphur with a pulsed laser (266 nm).

Precise Synthesis of Poly(thioester)s with Diverse Structures by Copolymerization of Cyclic Thioanhydrides and Episulfides Mediated by Organic Ammonium Salts

Yue, Tian-Jun,Zhang, Ming-Chao,Gu, Ge-Ge,Wang, Li-Yang,Ren, Wei-Min,Lu, Xiao-Bing

supporting information, p. 618 - 623 (2019/01/04)

The precise synthesis of poly(thioester)s with diverse structures is still a significant challenge in the polymeric materials field. Herein, we report a novel approach to the synthesis of well-defined poly(thioester)s by the controlled alternating copolymerization of cyclic thioanhydrides and episulfides induced by simple organic ammonium salts. Both the cation and anion have strong effects on the copolymerization. [PPN]OAc ([PPN]=bis(triphenylphosphine)iminium) with a bulky cation was proven to be efficient in initiating this polymerization, yielding poly(thioester)s with a completely alternating structure, controlled molecular weight, and narrow polydispersity. The poly(thioester) obtained from succinic thioanhydride and propylene sulfide is a typical semicrystalline material, possessing a high refractive index of up to 1.78. Because it uses readily available monomers, this method is expected to open up a new route to poly(thioester)s with diverse structures and properties.

Safe and Metal-Free Synthesis of 1-Alkenyl Aryl Sulfides and Their Sulfones from Thiiranes and Diaryliodonium Salts

Dong, Jun,Xu, Jiaxi

, p. 2407 - 2415 (2018/04/16)

A series of 1-alkenyl aryl sulfides was synthesized from thiiranes and diaryliodonium salts in tetrahydrofuran in the presence of potassium tert -butoxide. The proposed reaction mechanism involves generation of benzynes from the diaryliodonium salts in the presence of the base. Then, nucleophilic attack of the benzynes by thiiranes, followed by hydrogen abstraction and ring opening of the generated thiiranium intermediates, provides the sulfides. These sulfides were further oxidized with performic acid to the corresponding sulfones. The current method provides a metal-free and safe method for the preparation of 1-alkenyl aryl sulfides and their sulfones.
