98539-29-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98539-29-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,3 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98539-29:
(7*9)+(6*8)+(5*5)+(4*3)+(3*9)+(2*2)+(1*9)=188
188 % 10 = 8
So 98539-29-8 is a valid CAS Registry Number.

Paragraph 0258; 0259, (2017/07/26)

PURPOSE: A polymerizable naphthoic acid phenyl compound is provided to have high reflection anisotropy and high storage stability and high orientation. CONSTITUTION: A polymerizable naphthoic acid phenyl compound is represented by chemical formula 1. In chemical formula 1, one of M^1-M4 is a fluorine atom, a chlorine atom, a cyno group, a nitro group, a C1-7 alkyl group, a C1-7 alkoxy group, or a C1-7 alkanoyl group. L^1-L^6 is hydrogen, fluorine or chloride. A polymerizable liquid composition comprises the polymerizable compound. The polymer is obtained by polymerizing the polymerizable liquid compositions. An optical anisotropic object uses the polymer.
