654067-69-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 654067-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,4,0,6 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 654067-69:
(8*6)+(7*5)+(6*4)+(5*0)+(4*6)+(3*7)+(2*6)+(1*9)=173
173 % 10 = 3
So 654067-69-3 is a valid CAS Registry Number.

Low-cost dyes based on methylthiophene for high-performance dye-sensitized solar cells

Tian, Zongfang,Huang, Meihua,Zhao, Bin,Huang, Hui,Feng, Xiaoming,Nie, Yujuan,Shen, Ping,Tan, Songting

experimental part, p. 181 - 187 (2010/07/15)

Three donor-acceptor, π-conjugated (D-π-A) dyes containing methylthiophene or vinylene methylthiophene as π-conjugated spacer were utilised in dye-sensitized nanocrystalline TiO2 solar cells. The relationship between the structure of the dyes and their photophysical, electrochemical and photovoltaic properties was investigated systematically. The vinyl unit, introduced as the π-conjugated spacer, leads to unfavorable back-electron transfer and decrease of the open-circuit voltage. A dye-sensitized solar cell based on 2-cyano-3-(5-(4-(diphenylamino)phenyl)-4-methylthiophenyl-2-yl) acrylic acid displayed the most efficient solar-to-electricity conversion efficiency of the dyes with a maximum η value of 8.27% (Voc?=?0.72?V, Jsc?=?15.76?mA?cm-2, FF?=?0.73) under simulated AM 1.5 G solar irradiation (100?mW?cm-2).
