Calculate Digit Verification of CAS Registry Number 74225-18:
(7*7)+(6*4)+(5*2)+(4*2)+(3*5)+(2*1)+(1*8)=116
116 % 10 = 6
So 74225-18-6 is a valid CAS Registry Number.

Paragraph 0093, (2018/10/16)

PROBLEM TO BE SOLVED: To provide a novel liquid crystalline compound that is low in dielectric anisotropy, has responsiveness, and changes its birefringence by application of voltage. SOLUTION: The present invention provides a compound represented by formula (1) (In the formula (1), R1, R2 and R3 independently represent a hydrogen atom or C1-C10 alkyl, in the alkyl, at least one -CH2- may be substituted by -O-, -S-, -CO-, or -SiH2-, and at least one -(CH2)2- may be substituted by -CH=CH-or -C≡C-. n is an integer of 0-4. m is an integer of 1 or 2. Z1 and Z2 are -CH=CH-). SELECTED DRAWING: None COPYRIGHT: (C)2016,JPOandINPIT
