Check Digit Verification of cas no

The CAS Registry Mumber 1209-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1209-66:
(6*1)+(5*2)+(4*0)+(3*9)+(2*6)+(1*6)=61
61 % 10 = 1
So 1209-66-1 is a valid CAS Registry Number.

Phenothiazine dioxide based high triplet energy host materials for blue phosphorescent organic light-emitting diodes

Lee, In Ho,Lee, Jun Yeob

, p. 97903 - 97909 (2015)

Donor-acceptor type high triplet energy host materials were derived from a phenothiazine dioxide based electron transport moiety and a carbazole based hole transport moiety. Three phenothiazine dioxide type materials, 10-(3,5-di(9H-carbazol-9-yl)phenyl)-10H-phenothiazine 5,5-dioxide (DCzPO), 10-(3′,5′-di(9H-carbazol-9-yl)-[1,1′-biphenyl]-3-yl)-10H-phenothiazine 5,5-dioxide (DCzmPPO), and 10-(3′,5′-di(9H-carbazol-9-yl)-[1,1′-biphenyl]-4-yl)-10H-phenothiazine 5,5-dioxide (DCzpPPO), could transport both holes and electrons effectively and showed high triplet energy for use in blue phosphorescent organic light-emitting diodes. Device optimization of the DCzPO, DCzmPPO, and DCzpPPO host based blue devices could realize high EQE of 24.3%.

Aggregated-induced emission phenothiazine probe for selective ratiometric response of hypochlorite over other reactive oxygen species

Wang, Linlin,Hu, Yue,Qu, Yi,Xu, Jingli,Cao, Jian

, p. 54 - 59 (2016)

In order to perform a ratiometric fluorescent sensor to recognize hypochlorite over other reaction oxidation species, a simple phenothiazine probe (QC1) with double dioxaborolane moieties was designed and synthesized. QC1 provided blue emission in aqueous and solid state. Double dioxaborolane and quaternary phosphonium salt was introduced into the molecule to prevent aggregation. The sulphur atom at the centre of phenothiazine was to respond to the hypochlorite at room temperature over other ROS because of its stronger oxidized ability. QC1 gave good linear fitting in the ratiometric mode under both absorption and emission titration experiments. Moreover, QC1 showed lower detection limited that reached 0.95 μM in absorption titration and 0.41 μM in fluorescent titration process.

Cobalt Single-Atom-Intercalated Molybdenum Disulfide for Sulfide Oxidation with Exceptional Chemoselectivity

Chen, Zhongxin,Liu, Cuibo,Liu, Jia,Li, Jing,Xi, Shibo,Chi, Xiao,Xu, Haisen,Park, In-Hyeok,Peng, Xinwen,Li, Xing,Yu, Wei,Liu, Xiaowang,Zhong, Linxin,Leng, Kai,Huang, Wei,Koh, Ming Joo,Loh, Kian Ping

, (2019/12/03)

The identification of chemoselective oxidation process en route to fine chemicals and specialty chemicals is a long-standing pursuit in chemical synthesis. A vertically structured, cobalt single atom-intercalated molybdenum disulfide catalyst (Co1-in-MoS2) is developed for the chemoselective transformation of sulfides to sulfone derivatives. The single-atom encapsulation alters the electron structure of catalyst owing to confinement effect and strong metal–substrate interaction, thus enhancing adsorption of sulfides and chemoselective oxidation at the edge sites of MoS2 to achieve excellent yields of up to 99% for 34 examples. The synthetic scopes can be extended to sulfide-bearing alkenes, alkynes, aldehydes, ketones, boronic esters, and amines derivatives as a toolbox for the synthesis of high-value, multifunctional sulfones and late-stage functionalization of pharmaceuticals, e.g., Tamiflu. The synthetic utility of cobalt single atom-intercalated MoS2, together with its reusability, scalability, and simplified purification process, renders it promising for industrial productions.
