477949-72-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 477949-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,9,4 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 477949-72:
(8*4)+(7*7)+(6*7)+(5*9)+(4*4)+(3*9)+(2*7)+(1*2)=227
227 % 10 = 7
So 477949-72-7 is a valid CAS Registry Number.

The present invention provides a novel compound which is suitable as the starting material of a side-chain type liquid crystalline polymeric substance having a reactive group which is excellent in reactivity upon fixation of the liquid crystal orientation structure. The novel compound is a (meth)acrylic compound having an oxetanyl group represented by the formula wherein R1 is hydrogen or methyl, R2 is hydrogen, methyl, or ethyl, "-L1-M-L2-" represents a mesogen portion, and n and m are each an integer of 0 to 10. The present invention also provides a liquid crystal film containing the side-chain type liquid crystalline polymeric substance and a liquid crystal display mounted with such a liquid crystal film.
