Check Digit Verification of cas no

The CAS Registry Mumber 1283598-36-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,5,9 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1283598-36:
(9*1)+(8*2)+(7*8)+(6*3)+(5*5)+(4*9)+(3*8)+(2*3)+(1*6)=196
196 % 10 = 6
So 1283598-36-6 is a valid CAS Registry Number.

Highly crystalline new benzodithiophene-benzothiadiazole copolymer for efficient ternary polymer solar cells with an energy conversion efficiency of over 10%

Tamilavan, Vellaiappillai,Liu, Yanliang,Lee, Jihoon,Jung, Yun Kyung,Son, Semo,Jeong, Junghyun,Park, Sung Heum

, p. 4281 - 4289 (2018)

A new alternating polymer P(BDTSi-DFBT), poly(4,8-bis(triisopropylsilylethynyl)-benzo[1,2-b:4,5-b′]dithiophene-alt-5,6-difluoro-4,7-bis(4-octylthiophen-2-yl)benzo[c][1,2,5]thiadiazole), was prepared via Stille polymerization. The determined absorption maximum and optical band-gap (Eg) of P(BDTSi-DFBT) were 590 nm and 1.74 eV, respectively. The calculated highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels of P(BDTSi-DFBT) were -5.45 eV and -3.71 eV, respectively. The X-ray diffraction (XRD) analysis confirmed that P(BDTSi-DFBT) is a crystalline polymer. The binary-polymer solar cells, ITO/PEDOT:PSS/P(BDTSi-DFBT):PC70BM (1:1.5 wt%) + 3 vol% DIO/Al, made from P(BDTSi-DFBT) gave a power conversion efficiency (PCE) of 5.02% with an open-circuit voltage (Voc) of 0.81 V, a short-circuit current (Jsc) of 11.68 mA cm-2, and a fill factor (FF) of 53%. Conversely, the ternary-polymer solar cells, ITO/PEDOT:PSS/PTB7-Th:P(BDTSi-DFBT):PC70BM (0.8:0.2:1.5 wt%) + 3 vol% DIO/Al, made with a synthesized medium band-gap P(BDTSi-DFBT) and low band-gap PTB7-Th, offered a maximum PCE of 10.05%, with a Voc of 0.79 V, a Jsc of 17.92 mA cm-2, and a FF of 71%.

5,6-Difluorobenzothiadiazole and silafluorene based conjugated polymers for organic photovoltaic cells

, p. 5116 - 5123 (2014/07/07)

To achieve 5,6-difluorobenzothiadiazole and 2,7-linked silafluorene based soluble conjugated polymers, flexible side chains were attached at different positions of the conjugated polymers. Three soluble polymers PSiF-D(OT)DFBT, PSiF-TTDFBT, and PDOSiF-DTDFBT were prepared and used as donor materials for polymer solar cells. PSiF-D(OT)DFBT exhibits a band gap of 2.06 eV with a deep HOMO of -5.64 eV. PSiF-TTDFBT shows a band gap of 1.75 eV with the HOMO of -5.23 eV. PDOSiF-DTDFBT is of a band gap of 1.86 eV with the HOMO level of -5.37 eV. Among these three polymers, PDOSiF-DTDFBT shows the highest field effect transistor (FET) hole mobility up to 3.31 × 10-2 cm2 V-1 s-1, PDOSiF-DTDFBT:PC71BM blend films show the highest SCLC mobility up to 5.10 × 10-4 cm2 V-1 s-1, and polymer solar cells (PSCs) with the blend of PDOSiF-DTDFBT:PC71BM (1:1, by weight) as the active layer gave a power conversion efficiency (PCE) of 4.03% with an open circuit voltage (V oc) of 0.73 V, a short circuit current (Jsc) of 8.55 mA cm-2, and a fill factor (FF) of 0.65. Our studies also reveal the structure-property relationship of 2,7-linked silafluorene and 5,6-difluorobenzothiadiazole based conjugated polymers.
