Check Digit Verification of cas no

The CAS Registry Mumber 75838-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,3 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75838-38:
(7*7)+(6*5)+(5*8)+(4*3)+(3*8)+(2*3)+(1*8)=169
169 % 10 = 9
So 75838-38-9 is a valid CAS Registry Number.

High birefringence bistolane liquid crystals: Synthesis and properties

W?g?owska, Dorota,Kula, Przemys?aw,Herman, Jakub

, p. 403 - 408 (2016/01/09)

Twenty liquid crystals both symmetrical and non-symmetrical bistolanes with terminal alkyl, alkoxy and alkylsulfanyl chain and lateral methyl or ethyl group have been synthesized via Sonogashira cross-coupling and their mesomorphic properties have been studied. Most compounds exhibit an enantiotropic nematic phase in a broad temperature range (>40 °C). Optical properties of selected compounds have been investigated. They exhibit a high value of birefringence (>0.4).

Oligomerization of (diacetoxyiodo)benzene with trifluoromethanesulfonic acid. Preparation and structure of hypervalent iodine oligomers

Kitamura, Tsugio,Wakimoto, Ichiro,Nakamura, Tetsu,Fujiwara, Yuzo

, p. 253 - 255 (2008/02/13)

(equation presented) Treatment of (diacetoxyiodo)benzene with an excess amount of trifluoromethanesulfonic acid (TfOH) gives hypervalent iodine oligomers after quenching by aqueous NaBr. The thermolysis by KI yielding p-diiodobenzene and iodobenzene indicates that the structure for the oligomers consists of p-phenylene unit. The iodine oligomers in situ generated react with aromatic substrates such as benzene, toluene, and chlorobenzene to give the corresponding arylated iodine oligomers.
