Check Digit Verification of cas no

The CAS Registry Mumber 1443987-10-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,9,8 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1443987-10:
(9*1)+(8*4)+(7*4)+(6*3)+(5*9)+(4*8)+(3*7)+(2*1)+(1*0)=187
187 % 10 = 7
So 1443987-10-7 is a valid CAS Registry Number.

Donor-acceptor segregated paracyclophanes composed of naphthobipyrrole and stacked fluoroarenes

supporting information, p. 3202 - 3205 (2013/07/26)

The expeditious synthesis of donor-acceptor segregated paracyclophanes has been achieved by a selective SNAr reaction of hexafluorobenzene with o-dipyrrolylbenzenes and subsequent cyclodehydrogenation. An orthogonally arranged D-A segregated structure was confirmed by X-ray crystallography. The combined results of DFT calculations and absorption spectra revealed the charge transfer (CT) nature from the naphthobipyrrole (donor) to the stacked fluoroarene moiety (acceptor).
