891780-16-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 891780-16-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,1,7,8 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 891780-16:
(8*8)+(7*9)+(6*1)+(5*7)+(4*8)+(3*0)+(2*1)+(1*6)=208
208 % 10 = 8
So 891780-16-8 is a valid CAS Registry Number.

Syntheses, structure, and optical properties of ladder-type fused azaborines
Agou, Tomohiro,Kobayashi, Junji,Kawashima, Takayuki
, p. 2241 - 2244 (2006)
Ladder-type fused azaborines were synthesized. X-ray crystallographic analysis of a pentacene-type molecule shown here revealed the planarity of a fused azaborine. It was revealed by UV-vis and fluorescence spectra that such fused molecular structures are
