Check Digit Verification of cas no
The CAS Registry Mumber 1334686-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,6,8 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1334686-71:
(9*1)+(8*3)+(7*3)+(6*4)+(5*6)+(4*8)+(3*6)+(2*7)+(1*1)=173
173 % 10 = 3
So 1334686-71-3 is a valid CAS Registry Number.

Four π-conjugated benzo[1,2-b:4,5-b′]dithiophene (BDT) based polymers were synthesized for application in polymer solar cells. These polymers possessed desirable HOMO/LUMO levels for polymer photovoltaic applications. PBDTT-TTz and PBDTT-DTBT displayed strong absorption in the range of 300-650 nm, while PBDTT-DPP and PBDTT-TTDPP showed a further 100 nm extended absorption band. The lowest unoccupied molecular orbital energy levels of polymers were tuned effectively from -3.34 eV to -3.81 eV by fusing with different accepting units. A maximum power conversion efficiency of 2.60% was obtained from photovoltaic cells with a PBDTT-TTz:PC61BM (1:2, w/w) blend film as the active layer, with a short circuit current density of 8.37 mA cm-2, an open circuit voltage of 0.70 V, and a fill factor of 44.3%.
