222851-56-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 222851-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,8,5 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 222851-56:
(8*2)+(7*2)+(6*2)+(5*8)+(4*5)+(3*1)+(2*5)+(1*6)=121
121 % 10 = 1
So 222851-56-1 is a valid CAS Registry Number.

Anthrathiadiazole Derivatives: Synthesis, Physical Properties and Two-photon Absorption

Fan, Mingxuan,Chen, Guangsheng,Xiang, Yu,Li, Junbo,Yu, Xianglin,Zhang, Wenying,Long, Xueting,Xu, Liang,Wu, Jinjun,Xu, Ze,Zhang, Qichun

, p. 10898 - 10902 (2021/06/28)

Anthrathiadiazole is a key synthon for the construction of large azaacenes, however, the attachment of different substituents onto the skeleton of anthrathiadiazole is difficult but highly desirable because it could be easy to enrich the structures of aza

Synthesis of benzo-ortho-thiazines S-oxides by diels-alder reaction of N-sulfinylanilines with norbornadiene

Veremeichik,Merabov,Chuiko,Lodochnikova,Plemenkov

, p. 1605 - 1609 (2014/02/14)

From substituted N-sulfinylanilines acting as dienes in the Diels-Alder reaction with norbornadiene S-oxides of benzo-ortho-thiazines were obtained, which were oxidized into the corresponding S,S-dioxides belonging to the class of hybrid thiazinesulfonami

Aceno[2,1,3]thiadiazoles for field-effect transistors: Synthesis and crystal packing

Lei, Ting,Zhou, Yan,Cheng, Chu-Yang,Cao, Yue,Peng, Yang,Bian, Jiang,Pei, Jian

supporting information; experimental part, p. 2642 - 2645 (2011/07/08)

An efficient synthetic approach to a series of aceno[2,1,3]thiadiazole derivatives is described. 2-TIPS and 2-TES molecules exhibited different crystal packings, and 2-TIPS show good device performances with hole mobility up to 0.4 cm2 V-1 s-1 and an average mobility of 0.15 cm2 V-1 s-1 as the active material for organic field-effect transistors. All of the results demonstrate these aceno[2,1,3]thiadiazole derivatives as promising materials for optoelectronic devices.
