Check Digit Verification of cas no

The CAS Registry Mumber 918137-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,1,3 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 918137-84:
(8*9)+(7*1)+(6*8)+(5*1)+(4*3)+(3*7)+(2*8)+(1*4)=185
185 % 10 = 5
So 918137-84-5 is a valid CAS Registry Number.

Synthesis and optical properties of starburst carbazoles based on 9-phenylcarbazole core

Feng, Guo-Liang,Ji, Shun-Jun,Lai, Wen-Yong,Huang, Wei

, p. 2841 - 2845 (2008/02/13)

New well-defined starburst carbazole derivatives, which contain N-phenylcarbazole as the central core joining 9-hexylcarbazole or 9-phenylcarbazole as arms, are presented. All these compounds were obtained via Suzuki cross-coupling in moderate yields. Their structures were confirmed by 1H NMR, MALDI-TOF mass spectrometry and elementary analysis. Moreover, the fluorescence spectra showed that these compounds exhibited good blue fluorescence with the maximum wavelengths ranging from 410 nm to 430 nm. Georg Thieme Verlag Stuttgart.
