Check Digit Verification of cas no

The CAS Registry Mumber 18737-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,3 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18737-40:
(7*1)+(6*8)+(5*7)+(4*3)+(3*7)+(2*4)+(1*0)=131
131 % 10 = 1
So 18737-40-1 is a valid CAS Registry Number.

Silicon-containing dendritic tris-cyclometalated Ir(iii) complex and its electrophosphorescence in a polymer host

You, Youngmin,An, Cheng-Guo,Lee, Deug-Sang,Kim, Jang-Joo,Park, Soo Young

, p. 4706 - 4713 (2006)

In this paper, we present the synthesis and characterization of a new highly phosphorescent cyclometalated Ir(iii) complex with a silane-based dendritic substituent. The Ir(iii) complex showed 74 ± 3% of absolute phosphorescence quantum efficiency in the film state. In addition, efficient electrophosphorescence (32.8 cd A-1) employing an Ir(iii) complex-poly(N-vinylcarbazole) system device is observed. Study of a series of electroluminescent, spectroscopic, and electrochemical data of the Ir(iii) complex and the reference Ir(ppy)3 reveals superior performance of the new Ir(iii) complex.

Highly thermally-stable 4,4′-bis(4″-triphenylsilylphenyl)-1,1′- binaphthalene as the ultraviolet amplified spontaneous emitter, efficient host and deep-blue emitting material

, p. 266 - 272 (2016)

We report herein the synthesis and characterization of an efficient versatile binaphthyl derivative, 4,4′-bis(4″-triphenylsilylphenyl)-1,1′-binaphthalene (SiBN) with a high glass transition temperature of 159.3 °C. Its role as a lasing dye was demonstrated by the amplified spontaneous emission, which exhibited an ultraviolet peak of 397 nm with a low threshold of 20 μJ/pulse. Meanwhile, the lasing film and blue electroluminescent device employing this novel binaphthyl derivative as the host showed superior performances to the reference based on the conventional host 4,4′-bis(carbazol-9-yl)biphenyl. Finally, extremely stable colour-tunable deep-blue (436 nm/472 nm) organic electroluminescent devices based on SiBN were demonstrated with very high brightness (>7521.2 cd/m2) and high external quantum efficiencies (1.90% for 436 nm and 4.66% for 472 nm emission). The development of such functional versatility materials will be an effective method for reducing the cost of organic photoelectric devices.
