137635-70-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137635-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,3 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137635-70:
(8*1)+(7*3)+(6*7)+(5*6)+(4*3)+(3*5)+(2*7)+(1*0)=142
142 % 10 = 2
So 137635-70-2 is a valid CAS Registry Number.

5,5-Dialkyl-δ-valerolactone Derivatives as New Chiral Dopants for Ferroelectric Liquid Crystals

Sakashita, Keiichi,Nakaoka, Yuriko,Ikemoto, Tetsuya,Terada, Fumiko,Kageyama, Yoshitaka,et al.

, p. 1727 - 1730 (2007/10/02)

(S)-2-(4'-Octyloxybiphenyl-4-carboxy)-5,5-dipropyl-δ-valerolactone showed interesting properties as the chiral dopant for ferroelectric liquid crystals (FLCs).The FLC mixture containing only 2percent by mol of this compound exhibited the magnitude of spontaneous polarization (Ps) as large as 9.6 nC/cm2 and the response time as fast as 75 μs at 25 deg C in the electric field of +/- 5 V/μm.
