Additionally, the unique structure of 2,5-diethynyl-1,4-phenylenediamine makes it a valuable tool for the development of advanced organic electronic materials.
Check Digit Verification of cas no
The CAS Registry Mumber 1141727-54-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,1,7,2 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1141727-54:
(9*1)+(8*1)+(7*4)+(6*1)+(5*7)+(4*2)+(3*7)+(2*5)+(1*4)=129
129 % 10 = 9
So 1141727-54-9 is a valid CAS Registry Number.

Benzodipyrrole-based Donor–Acceptor-type Boron Complexes as Tunable Near-infrared-Absorbing Materials
Nakamura, Tomoya,Furukawa, Shunsuke,Nakamura, Eiichi
, p. 2016 - 2020 (2016)
Benzodipyrrole-based donor–acceptor boron complexes were designed and synthesized as near-infrared-absorbing materials. The electron-rich organic framework combined with the Lewis acidic boron co-ordination enabled us to tune the LUMO energy level and the HOMO–LUMO gap (i.e.,the absorption wavelength) by changing the organic acceptor units, the number of boron atoms, and the substituents on the boron atoms.
