859771-23-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 859771-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,9,7,7 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 859771-23:
(8*8)+(7*5)+(6*9)+(5*7)+(4*7)+(3*1)+(2*2)+(1*3)=226
226 % 10 = 6
So 859771-23-6 is a valid CAS Registry Number.

o-Carboranes C-functionalized by (4-substituted-phen-1-yl)ethynyl-1,4-phenyl groups or (2-substituted-fluoren-7-yl)ethynyl-2,7-fluorenyl groups, in which the pendant functionalization is electron-withdrawing nitro or electron-donating diphenylamino groups

Synthesis, two- and three-photon absorption, and optical limiting properties of fluorene-containing ferrocene derivatives

Zheng, Qingdong,He, Guang S.,Lu, Changgui,Prasad, Paras N.

, p. 3488 - 3493 (2007/10/03)

The synthesis and characterization of two novel fluorene-containing ferrocene derivatives were reported. The two-photon absorption spectra and three-photon absorption cross-section values in the IR region for these two chromophores were studied. Together
