Check Digit Verification of cas no

The CAS Registry Mumber 18013-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,1 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18013-97:
(7*1)+(6*8)+(5*0)+(4*1)+(3*3)+(2*9)+(1*7)=93
93 % 10 = 3
So 18013-97-3 is a valid CAS Registry Number.

Fluorescence response of cruciform D-π-A-π-D phenothiazine derivatives to mechanical force

Zhang, Tong,Zhang, Chunyu,Li, Xiaoting,Liang, Meng,Bian, Weixiao,Zhang, Yan,Wang, Kunpeng,Xue, Pengchong

, p. 4192 - 4199 (2019)

Two cruciform D-π-A-π-D phenothiazine derivatives with two ester groups as electron-withdrawing moieties (i.e., EPTD and BPTD, with ethyl and butyl groups, respectively) were synthesized, and their responses to mechanical force stimuli were investigated. EPTD was found to have two polymorphs, namely, EPTD-Y and EPTD-R, with yellow and orange-red fluorescence, respectively. Single-crystal analysis illustrated that strong π-stacking affirmed by a short interplanar distance of 2.98 ? existed in the EPTD-Y crystal, which caused a large red-shift of 72 nm in the absorption spectrum. Meanwhile, although the π-stacking distance reached 3.74 ?, the electrostatic attraction between ester and phenothiazine moieties as an acceptor and donor, respectively, existed in the EPTD-R crystal, which may be responsible for its long emission wavelength. EPTD-R maintained its π-stacking after applying a mechanical force stimulus because its absorption and emission bands only slightly shifted. A fluorescence change from yellow to red occurred for the EPTD-Y crystal after grinding. The spectral results suggested that similar π-stacking existed in EPTD-R and EPTD-Y ground powders and was identical to that in the EPTD-R crystal. In addition, the BPTD crystal emitted green fluorescence due to weak π-stacking induced by a large stacking distance of 4.15 ?. Interestingly, it also changed its fluorescence into red after grinding because of the presence of π-stacking similar to that of the EPTD-R ground solid. Thus, π-stacking can be determined in three amorphous solids.

A Series of Lanthanide Coordination Polymers Based on Designed Bifunctional 1,4-Bis(imidazol-1-yl)terephthalic Acid Ligand: Structural Diversities, Luminescence, and Magnetic Properties

Zhang, Xiu-Tang,Fan, Li-Ming,Fan, Wei-Liu,Li, Bin,Liu, Guang-Zeng,Liu, Xin-Zheng,Zhao, Xian

, p. 3993 - 4004 (2016/07/16)

On the basis of the designed bifunctional 1,4-bis(imidazol-1-yl)terephthalic acid (H2BTA) ligand, a series of three-dimensional lanthanide coordination polymers, namely, [La2(BTA)1.5(ox)1.5(H2O)3]n (1), [Nd(BTA)(ox)0.5(H2O)]n (2), {[Ln(HBTA)(ox)(H2O)]·xH2O}n (Ln = Pr for 3 (x = 0), Sm for 4 (x = 0), Dy for 5 (x = 1.5), and Eu for 6 (x = 1)), and [Ln(BTA)(SO4)0.5(H2O)]n (Ln = Eu for 7, and Tb for 8) were obtained with the help of oxalate or sulfate ions. On the basis of the binuclear La2 secondary building unit (SBUs), the framework of 1 displays an unprecedented (3,3,4,9)-connected net with the point symbol of (411.55.614.75.8)2(42.5)2(43)2(44.62). While in complex 2, the binuclear Nd2 SBUs are connected by the BTA2- ligands to generate an interestingly (4,10)-connected (412.516.612.75)(46)2 net. Complexes 3-6 are isomorphism and show a 2-fold interpenetrated 4-connected (66)-dia net. Complexes 7 and 8 are isomorphism and show a novel (4,5)-connected (44.62)(44.66) net. Photoluminescence investigations show that 2 is a good near-infrared luminescent material, and 4 is a rarely reported single component white light emitting material. Complexes 6 and 7 show typically red emission, while complex 8 shows typically green emission, which can be used as a red or green emitting phosphor. Moreover, the luminescent lifetimes and quantum yields of the titled complexes were investigated. The magnetic susceptibility data of 2 indicated there are antiferromagnetic interactions between the NdIII ions.
