Check Digit Verification of cas no
The CAS Registry Mumber 214-17-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,1 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 214-17:
(5*2)+(4*1)+(3*4)+(2*1)+(1*7)=35
35 % 10 = 5
So 214-17-5 is a valid CAS Registry Number.

Characterization of the combustion products of polyethylene
Piao, Mingjun,Chu, Shaogang,Zheng, Minghui,Xu, Xiaobai
, p. 1497 - 1512 (2007/10/03)
Polyethylene (PE) was burned in a tube-type furnace with an air flow at a temperature of 600~900°C. Combustion products were collected with glass wool, glass fiber filter, and XAD-2 adsorbent. The analysis of the products was performed with GC-FID and GC-MSD. At low temperature, hydrocarbons were the major components, while at higher temperature the products were composed of polycyclic aromatic hydrocarbons. With the high performance of the Hewlett-Packard 6890GC-5973MSD, more compounds were identified in comparison with previous studies.
Photoisomerization and Photocyclization Reactions of 1-Styrylanthracene
Karatsu, Takashi,Kitamura, Akihide,Zeng, Hualing,Arai, Tatsuo,Sakuragi, Hirochika,Tokumaru, Katsumi

On triplet sensitization, 1-styrylanthracene (1SA) undergoes adiabatic cis->trans one-way isomerization (3c*->3t*) similarly to 2-anthrylethylenes.However, upon direct irradiation, cis-1SA in the singlet excited state mostly undergoes cyclization to a dihydrophenanthrene-type product (DHP), 4a,4b-dihydrobenzochrysene, competing with an inefficient intersystem crossing to 3c* followed by one-way isomerization.The produced DHP, in deaerated benzene, is reverted to cis-1SA by a thermal (Ea = 14.9 kcal mol-1) or a photochemical pathway; however, under an oxygenated atmosphere DHP gives benzochrysene.A failure in the production of a cyclized product upon the excitation of trans-1SA shows that the isomerization really takes place in a one-way fashion.
