Check Digit Verification of cas no

The CAS Registry Mumber 78025-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,2 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78025-01:
(7*7)+(6*8)+(5*0)+(4*2)+(3*5)+(2*0)+(1*1)=121
121 % 10 = 1
So 78025-01-1 is a valid CAS Registry Number.

A new luminescent metal-organic framework based on dicarboxyl-substituted tetraphenylethene for efficient detection of nitro-containing explosives and antibiotics in aqueous media

Liu, Xun-Gao,Tao, Chen-Lei,Yu, Huang-Qin,Chen, Bin,Liu, Zhen,Zhu, Gen-Ping,Zhao, Zujin,Shen, Liang,Tang, Ben Zhong

, p. 2983 - 2988 (2018)

In this work, we synthesized a dicarboxyl-substituted tetraphenylethene (TPE) ligand, 4,4′-(1,2-diphenylethene-1,2-diyl)dibenzoic acid (H2BCTPE), with a prominent aggregation-induced emission (AIE) feature. A two-fold interpenetrated luminescen

Molecular association-induced emission shifts for E/Z isomers and selective sensing of nitroaromatic explosives

Hurlock, Matthew J.,Kan, Yuwei,Le?rivain, Thibaut,Lapka, Joseph,Nash, Kenneth L.,Zhang, Qiang

, p. 6197 - 6203 (2018/09/25)

Two 1,2-disubstituted tetraphenylethene E/Z isomers, each containing two cyano functional groups, were successfully synthesized and characterized. Unlike conventional tetraphenylethene molecules, the two isomers possess unique aggregation induced emission red-shift and enhancement behavior. Interestingly, the crystalline solids of these two isomers show distinct emission maxima, which are more than 50 nm apart from each other. These two isomers can selectively detect nitroaromatics, showing a quenching efficiency of picric acid more than 100 times higher than other nitroaromatics. The structural characterization, absorption, and emission in solutions as well as DFT calculations were conducted to help us gain deep insights into the chemistry of these species.

Merostabilization in radical ions, triplets, and biradicals. 6. The excited state behaviour of para-substituted tetraphenylethylenes

Leigh, William J.,Arnold, Donald R.

, p. 3061 - 3075 (2007/10/02)

The half-wave oxidation and reduction potentials, measured by cyclic voltammetry, of tetraphenylethylene and a series of para-substituted (cyano, methyl, and methoxy) derivatives are found to correlate with ?+ and ?- values respectively.The deviations from these correlations that are observed for one of the derivatives (unsymmetrically substituted) are attributed to merostabilization.The nature of the first excited singlet state of these compounds is investigated by spectroscopic and photochemical means.Quantum yields for the direct cis-trans photoisomerization demonstrate that this provides the dominant pathway for decay of the singlet state.The ?,?* triplet energies are estimated from a qualitative investigation of the relative efficiencies of triplet-sensitized cis-trans isomerization as a function of sensitizer triplet energy.
