Check Digit Verification of cas no

The CAS Registry Mumber 59214-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,2,1 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 59214-70:
(7*5)+(6*9)+(5*2)+(4*1)+(3*4)+(2*7)+(1*0)=129
129 % 10 = 9
So 59214-70-9 is a valid CAS Registry Number.

Triple Oxa[7]helicene with Circularly Polarized Luminescence: Enhancing the Dissymmetry Factors via Helicene Subunit Multiplication

Zhou, Fulin,Huang, Zhenmei,Huang, Zhongyan,Cheng, Rui,Yang, Yudong,You, Jingsong

, p. 4559 - 4563 (2021)

The development of multiple heterohelicenes with a high luminescence dissymmetry factor (glum) is an appealing yet challenging task. Herein, we disclose the synthesis of a structurally unusual furan-based triple oxa[7]helicene, which represents the first reported triple hetero[7]helicene, via [2+2+2] cyclotrimerization/intramolecular dehydrogenative annulation. Compared to the reported double oxa[7]helicene, the triple oxa[7]helicene exhibits an improved glum value of 1.8 × 10-3, exemplifying the potential of the helicene subunit multiplication approach to enhance the glum of heterohelicenes.

A series of π-extended thiadiazoles fused with electron-donating heteroaromatic moieties: Synthesis, properties, and polymorphic crystals

Kato, Shin-Ichiro,Furuya, Takayuki,Nitani, Masashi,Hasebe, Naoya,Ie, Yutaka,Aso, Yoshio,Yoshihara, Toshitada,Tobita, Seiji,Nakamura, Yosuke

, p. 3115 - 3128 (2015)

π-Extended thiadiazoles 4-8 fused with various electron-donating heteroaromatic moieties have been designed and synthesized. Just like thiadiazoles 1-3 synthesized previously, 4-8 exhibit intramolecular charge-transfer (CT) interactions, moderate-to-good fluorescence quantum yields of up to 0.78, and electrochemical amphoterism. In comparison with 1-3, the benzannulation in thiadiazoles 4-7 moderately extends the p conjugation and significantly increases the stability of the cationic species formed upon electrochemical oxidation. The fluorescence quantum yields increase remarkably from 3 to 6 and 7 due to the efficient suppression of nonradiative intersystem crossing resulting from the benzannulation. The properties of 4-8 strongly reflect the different species annulated to the pyrrole rings, namely benzothiophene, naphthalene, and benzofuran. Eleven crystals, including poly- and pseudopolymorphic crystals of 1 (1-Crys.(Y ) and 1-Crys.(G)), 2 (2-Crys.(O) and 2-Crys.(G)), 4 (4-Crys.(O) and 4-Crys. (G)), and 6 (6-Crys.(O) and 6-Crys.(G)), were obtained and characterized by X-ray crystallography. The fluorescence colors and efficiencies are distinct for each poly- and pseudopolymorph of 1, 2, 4, and 6. It has been suggested that both the extent of the electronic interactions in the π-stacked dimers and the presence of excitonic interactions originating in the 1D face-to-face slipped columns affect the fluorescence wavelengths of the poly- and pseudopolymorphs.
