66016-16-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66016-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,0,1 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66016-16:
(7*6)+(6*6)+(5*0)+(4*1)+(3*6)+(2*1)+(1*6)=108
108 % 10 = 8
So 66016-16-8 is a valid CAS Registry Number.

Cyclobutanecarboxylic acid derivatives and liquid crystalline compositions containing them

, (2008/06/13)

An optically inactive cyclobutanecarboxylic acid derivative of the general formula STR1 wherein R1 is a hydrogen atom or a straight or branched chain alkyl group having 1-14 carbon atoms, R2 is a straight or branched chain alkyl grou

Synthesis and liquid crystal properties of compounds incorporating cyclobutane, spiroheptane and dispirodecane rings

Chain, L. K. M.,Gemmel, P. A.,Gray, G. W.,Lacey, D.,Toyne, K. J.

, p. 113 - 140 (2007/10/02)

A number of esters of structure (I) incorporating the cyclobutane, spiroheptane, or dispirodecane rings has been prepared using a diethyl malonate synthesis.Strict comparison of the liquid crystal behaviour amongst the three classes containing a terminal cyano-substituent was not possible because both the cyclobutanes and dispirodecanes are mixtures of cis- and trans-isomers; the spiroheptanes are racemic systems.Using preparative hplc, it was however possible to isolate the pure cis- and trans-isomers of two of the cyano-substituted cyclobutane esters (I; R = alkyl, -X- = --, Y = CN).From the physical data and the results for the corresponding spiroheptane esters, conclusions regarding the effects of these ring systems on liquid crystal behaviour were obtained.The pure cis- and trans-isomers of the cyclobutane ester (I, R = C3H7, -X- = --, Y = CN) have been assessed for the trends in both order parameter and viscosity with temperature; the results support the idea that idea that the trans-cyclobutane ring adopts a more planar conformation at higher temperatures.Keywords: cyclobutane- and related spiro-systems, cis-/trans-isomerism, order parameter, briefringence, viscosity, structure/property relations.

Cyclobutyl substituted derivatives of prostaglandin analogs

-

, (2008/06/13)

Novel C15 cyclobutyl analogs or derivatives of prostaglandins of the E-, A- and F-classes are useful modifiers of smooth muscle activity. The compounds have valuable pharmacological properties such as platelet antiaggregating agents, gastric antisecretory agents and brochodilating agents.
