Check Digit Verification of cas no

The CAS Registry Mumber 165820-78-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,8,2 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 165820-78:
(8*1)+(7*6)+(6*5)+(5*8)+(4*2)+(3*0)+(2*7)+(1*8)=150
150 % 10 = 0
So 165820-78-0 is a valid CAS Registry Number.

Helically Twisted Benzene-1,3,5-triamine-fused Porphyrin Dimers

Kato, Kenichi,Osuka, Atsuhiro

, p. 517 - 520 (2020)

NiII-2,18-dibromo-20-chloroporphyrin was fused with N 1,N 3,N 5-triaryl-1,3,5-benzenetriamine via t-BuONa-promoted one-pot reaction to give a helically twisted nitrogen-doped fused porphyrin dimer with high selectivity instead of a trimeric porphyrin. The dimer shows a red-shifted and broad electronic absorption spectrum and negatively shifted multi-stage oxidation behavior owing to the significant electronic effect of the embedded amine-type nitrogen atoms and inter-porphyrinic interaction. Bis-NiII-dimer was successfully converted to the corresponding bis-ZnII-complex, which exhibits fluorescence at around 650700 nm.
