General Description
Benzol, 1-[(4-methoxyphynyl)ethinyl]-, 4-4-propylcyclohexyl)-, trans- is a type of organic compound considered complex due to the structure it possesses. It consists of an aromatic benzol group, with a methoxyphenyl ethinyl substitution at one position. This chemical has another substitution involving propylcyclohexyl at its fourth position. The 'trans-' prefix in its name signifies the geometric isomerism in the compound, indicating that certain groups are on opposite sides of the double bond. Detailed information regarding its properties, reactivity, uses, or potential health effects is not readily available, which is often the case with such specific and complex compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 116903-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,0 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 116903-47:
(8*1)+(7*1)+(6*6)+(5*9)+(4*0)+(3*3)+(2*4)+(1*7)=120
120 % 10 = 0
So 116903-47-0 is a valid CAS Registry Number.

An improved practical synthesis of liquid crystals of trans- cyclohexyltolans by Sonogashira cross-coupling reaction of 1-iodo- 4-(trans-4-alkylcyclohexyl)benzene with aromatic terminal alkynes in the presence of Pd/C (palladium on activated carbon) as low as 0.03mol% of Pd and CuI (2mol%) in amixture solvent of acetone-water (5 : 2 in volume) is described. The liquid crystals could be obtained in high yields as a solid with excellent purity by simple filtration, and the filtrate could be reused several times while still retaining high catalytic activity.
