Check Digit Verification of cas no

The CAS Registry Mumber 251566-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,5,6 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 251566-01:
(8*2)+(7*5)+(6*1)+(5*5)+(4*6)+(3*6)+(2*0)+(1*1)=125
125 % 10 = 5
So 251566-01-5 is a valid CAS Registry Number.

The impact of adjusting auxiliary donors on the performance of dye-sensitized solar cells based on phenothiazine D-D-π-A sensitizers

Chen, Shu-Guang,Jia, Hai-Lang,Ju, Xue-Hai,Zheng, He-Gen

, p. 127 - 135 (2017)

Three new D-D-π-A sensitizers ZHG5, ZHG6 and ZHG7 have been prepared by gradually improving the steric hindrance of auxiliary donors and the power conversion efficiencies (PCE) are 5.64%, 5.32% and 2.74%. UV–Vis absorption indicates that the molar extinction coefficients decrease with the increased steric hindrance of auxiliary donors. X-ray photoelectron spectroscopy (XPS) indicates that the tilt angles of ZHG5 and ZHG6 anchored on the TiO2 film are similar and ZHG7 is almost standing rather vertical on the TiO2 film with the smallest tilt angle. The results of dye desorption and XPS experiments indicate that the dye loading amount of ZHG6 with larger steric hindrance is lower than that of ZHG5, ZHG7 with largest auxiliary donor has the maximum loading amount probably due to its smallest tilt angle. Larger auxiliary donor of ZHG6 leads to higher open circuit voltage (Voc = 734 mV) but lower shorter circuit current (Jsc = 12.63 mA cm?2) compared with that of ZHG5 (Voc = 730 mV, Jsc = 12.06 mA cm?2). However, dense packing of dye ZHG7 anchored on the TiO2 leads to more serious intermolecular π-π aggregation effects. Perhaps this effect and lowest molar extinction coefficient are the reason that DSSC based on ZHG7 have the lowest PCE. So above results indicate that auxiliary donor with overlarge steric hindrance will have smaller tilt angle of dye anchored on TiO2 and may lead to more dye loading amount but serious intermolecular π-π aggregation effects.

Synthesis and characterization of solution-processable highly branched iridium (III) complex cored dendrimer based on tetraphenylsilane dendron for host-free green phosphorescent organic light emitting diodes

Kim, Seul-Ong,Zhao, Qinghua,Thangaraju,Kim, Jang Joo,Kim, Yun-Hi,Kwon, Soon-Ki

experimental part, p. 139 - 145 (2011/12/04)

Solution processable highly branched iridium(III) complex fac-tris(2-phenylpyridyl)iridium-cored dendrimer based on tetraphenylsilane dendron and 2-ethylhexyloxy surface groups was prepared. The structure of dendrimer was confirmed by nuclear magnetic resonance, mass and infrared studies. Thermogravimetric analysis and differential scanning calorimetry studies show the thermal stability (T5%) of 625 K with high glass transition temperature of 423 K. Photoluminescence studies of dendrimer showed the core emission at 516 nm in solution and at 521 nm in film, indicating the highly branched non-conjugated tetrahedral tetraphenylsilane dendrons around the core highly inhibit the intermolecular interactions between the cores in the film. The solution processed green emitting phosphorescent organic light emitting diodes based on dendrimer were fabricated and characterized. The device using host free dendrimer as emitter showed the external quantum efficiency of 0.4%. The results show the potential of this new type of dendritic emitting structure in highly efficient solution processed host-free green phosphorescent organic light emitting diodes.
