1207563-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1207563-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,5,6 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1207563-57:
(9*1)+(8*2)+(7*0)+(6*7)+(5*5)+(4*6)+(3*3)+(2*5)+(1*7)=142
142 % 10 = 2
So 1207563-57-2 is a valid CAS Registry Number.

We synthesized new low polar derivatives of tetrahydropyran with nematic and smectic behaviour. Quantum chemical calculations show, that the most elongated conformers of the cyclohexane and tetrahydropyran derivatives have nearly identical molecular shape
