Check Digit Verification of cas no

The CAS Registry Mumber 15861-51-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,8,6 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15861-51:
(7*1)+(6*5)+(5*8)+(4*6)+(3*1)+(2*5)+(1*1)=115
115 % 10 = 5
So 15861-51-5 is a valid CAS Registry Number.

Transition metal complex, polymer, mixture, composition and organic electronic device

-

Paragraph 0273-0274; 0276-0277, (2021/06/26)

The invention discloses a transition metal complex, a polymer, a mixture, a composition and an organic electronic device. When the transition metal complex provided by the invention is used as a light-emitting layer doping material and is applied to an organic electronic device, especially an OLED, the light-emitting efficiency of the device can be improved, and the service life of the device can be prolonged.

Iodine-Promoted Tunable Synthesis of 2-Naphthyl Thioethers and 1-Naphthyl Thioethers

Bao, Yishu,Yang, Xiuqin,Dai, Zonghao,Ji, Suyu,Zhou, Qingfa,Yang, Fulai

supporting information, p. 2154 - 2158 (2019/04/13)

An iodine-promoted regioselective sulfenylation/deoxygenation/aromatization reaction of 1-tetralones with disulfides has been developed. This process could be modified to synthesize 2-naphthyl thioethers and 1-naphthyl thioethers in moderate to excellent

Photostimulated Reactions of o-Dihalobenzenes with Nucleophiles Derived from the 2-Naphthyl System. Competition between Electron Transfer, Fragmentation, and Ring Closure Reactions

Baumgartner, Maria T.,Pierini, Adriana B.,Rossi, Roberto A.

, p. 2593 - 2598 (2007/10/02)

The photostimulated reaction of o-dihalobenzenes 2 with 2-naphthoxide ions 1-O gave the substitution product on carbon 1 of the naphthyl moiety with retention of halogen (I, Br, and Cl) 3 as well as the ring closure product benzonaphtholfuran (4), with product 3 being an intermediate in the formation of 4.The products obtained in the photostimulated reaction of 2-naphthalenethiolate ions 1-S with 2 depend on the halogens.When both nucleofugal groups are iodine, only the ring closure product benzonaphthothiophene (10) is obtained.With o-bromoiodobenzene, the photostimulated reaction gave 10 and the substitution product on sulfur with retention of bromine, while with o-chloroiodobenzene the only observed product was the substitution product on sulfur with retention of chlorine.The photostimulated reaction of 2 with 2-naphthaleneselenolate ions 1-Se gave the same amount of cyclized product benzonaphthoselenophene (14) and the substitution product on selenium without retention of halogen 15, although in an overall low yield.It is suggested that all these reactions occur by the SRN1 mechanism.Theoretical studies support the different behavior found with the nucleophiles derived from the 2-naphthyl system.
