Check Digit Verification of cas no

The CAS Registry Mumber 1089687-05-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,6,8 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1089687-05:
(9*1)+(8*0)+(7*8)+(6*9)+(5*6)+(4*8)+(3*7)+(2*0)+(1*5)=207
207 % 10 = 7
So 1089687-05-7 is a valid CAS Registry Number.

Synthesis and photophysical properties of semiconductor molecules D1-A-D2-A-D1-type structure based on derivatives of quinoxaline and dithienosilole for organics solar cells

Keshtov,Godovsky, D. Yu,Kuklin,Nicolaev,Lee,Lim,Lee,Koukaras,Sharma, Ganesh D.

, p. 361 - 370 (2016)

A novel small molecule with D1-A-D2-A-D1 structure denoted as DTS(QxHT2)2 based on quinoxaline acceptor and dithienosilone donor units was synthesized and its optical and electrochemical properties were investigated. The thin film of DTS(QxHT2)2 showed a broad absorption profile covering the solar spectrum from 350?nm to 780?nm with an optical bandgap of 1.63?eV. The energy levels estimated from the cyclic voltammetry indicate that this small molecule is suitable as donor along with PC71BM as acceptor for the fabrication solution processed bulk heterojunction solar cells for efficient exciton dissociation and high open circuit voltage. The organic solar cells based on optimized DTS(QxHT2)2:PC71BM active layers processed with chloroform and DIO/CF showed overall power conversion efficiency of 3.16% and 6.30%, respectively. The higher power conversion efficiency of the solar cell based on the DIO/CF processed active layer is attributed to enhanced short circuit photocurrent and fill factor may be related to better phase separation between donor and acceptor in the active layer and more balanced charge transport, induced by the solvent additive. The power conversion efficiency of the organic solar cell was further improved up to 7.81% based on active layer processed with solvent additive, using CuSCN as hole transport layer instead of PEDOT:PSS and mainly attributed to increased fill factor and open circuit voltage due the formation of better Ohmic contact between the active layer and the CuSCN layer.

Low band gap dithieno[3,2-b:2′,3′-d]silole-containing polymers, synthesis, characterization and photovoltaic application

A series of low band gap silole-containing polymers were synthesized with different alkyl side chains and a power conversion efficiency (PCE) of 3.43% was obtained.

The end-capped group effect on dithienosilole trimer based small molecules for efficient organic photovoltaics

Li, Wei,Deng, Wanyuan,Wu, Kailong,Xie, Guohua,Yang, Chuluo,Wu, Hongbin,Cao, Yong

, p. 1972 - 1978 (2016/03/15)

Three new small molecules, FBT-tDTS, DFBT-tDTS and RHO-tDTS, were designed and synthesized by using a rigid dithienosilole trimer (tDTS) as the novel donor unit and 5-fluorobenzothiadiazole (FBT), 5,6-difluorobenzothiadiazole (DFBT) and 3-ethylrhodanine (RHO) as acceptor units, respectively. According to the density functional theory calculations, RHO-tDTS has a more rigid structure due to the linkage between the donor and acceptor units. As a result, RHO-tDTS exhibits a red-shifted absorption spectrum and a higher hole mobility in comparison with FBT-tDTS and DFBT-tDTS. Small molecule solar cells based on RHO-tDTS show a power conversion efficiency of 7.56%, significantly performing better than the other two analogues. The mechanism of the good photovoltaic performance of RHO-tDTS was discussed. We also demonstrated that the end-capped groups on small molecules play an important role in tuning the performance of the organic photovoltaic devices.
