170981-25-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 170981-25-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,9,8 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 170981-25:
(8*1)+(7*7)+(6*0)+(5*9)+(4*8)+(3*1)+(2*2)+(1*5)=146
146 % 10 = 6
So 170981-25-6 is a valid CAS Registry Number.

Highly efficient syntheses of 3-aryl-2-cycloalken-1-ones and an evaluation of their liquid crystalline properties
Marson,Farrand,Brettle,Dunmur
, p. 4377 - 4381 (2007/10/03)
Cycloalkenones are shown to be mesogens and can be synthesised in near quantitative yields by a convergent palladium(0)-catalysed cross-coupling strategy; a 2-methyl group induces a change of phase from smectic to nematic.
