Check Digit Verification of cas no

The CAS Registry Mumber 1331843-55-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,1,8,4 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1331843-55:
(9*1)+(8*3)+(7*3)+(6*1)+(5*8)+(4*4)+(3*3)+(2*5)+(1*5)=140
140 % 10 = 0
So 1331843-55-0 is a valid CAS Registry Number.

Synthesis, characterization, physical properties, and OLED application of single BN-fused perylene diimide

Li, Gang,Zhao, Yongbiao,Li, Junbo,Cao, Jun,Zhu, Jia,Sun, Xiao Wei,Zhang, Qichun

, p. 196 - 203 (2015)

It is very challenging to introduce azaborine into an electrondeficient arene system because of unfavorable intramolecular electrophilic borylation reaction. In this report, we adopted a straightforward methodology to construct a large BN-embedded π-syste

Self-assembled nanorods of bay functionalized perylenediimide: Cu2+ based 'turn-on' response for INH, complementary NOR/OR and TRANSFER logic functions and fluorosolvatochromism

Singh, Prabhpreet,Kumar, Kapil,Bhargava, Gaurav,Kumar, Subodh

, p. 2488 - 2497 (2016/07/14)

We designed and synthesized the mono bay functionalized perylenediimide (PDI) derivative PDI-DMEA which undergoes self-assembly to form a nanorod morphology. The diameter of these nanorods is in the range of 150-300 nm and the length extended up to the μm range. These nanorods on interaction with Cu2+ ions transformed into spherical aggregates having a diameter of 350-600 nm in accordance with DLS studies. In solution, PDI-DMEA shows a blue shift of the internal charge transfer (ICT) absorption band from 605 to 570 nm along with a hyperchromic effect at 570 nm, in the presence of 0.7 equivalents of Cu2+ ions. The addition of 2 equivalents of Cu2+ ions results in complete disappearance of the ICT band at 570 nm and appearance of a normal absorption band of PDI at 515 nm (a visual colour change from colourless to yellow). On the other hand PDI-DMEA shows a strong fluorescence 'turn-on' response at 537 and 573 nm on addition of higher equivalents of Cu2+ ions. Thus, PDI-DMEA represents several examples of molecular switches such as 'OFF-ON-OFF' and 'ON-OFF-ON' at 570/515 nm (Cu2+, absorbance), and 'OFF-ON' at 570 nm (Fe2+, absorbance) and 537 nm (Cu2+, fluorescence) and thus offers the possibility for developing NOR, OR, INH and TRANSFER logic and complimentary logic circuits. Moreover, PDI-DMEA and the PDI-DMEA-Cu2+ complex show fluorosolvatochromism which helps to develop a colour array for differentiating organic solvents. The detailed mechanism of interaction of Cu2+ and Fe2+ with PDI-DMEA, confocal laser scanning microscopic studies, dynamic light scattering, 1H NMR titration and reversibility are discussed.

1,6- and 1,7-Regioisomers of asymmetric and symmetric Perylene Bisimides: Synthesis, characterization and optical properties
