Check Digit Verification of cas no

The CAS Registry Mumber 1422464-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,4,6 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1422464-20:
(9*1)+(8*4)+(7*2)+(6*2)+(5*4)+(4*6)+(3*4)+(2*2)+(1*0)=127
127 % 10 = 7
So 1422464-20-7 is a valid CAS Registry Number.

Fluorine-Containing Aromatic Compound and Method for Producing Same

-

Paragraph 0118; 0119; 0120; 0121; 0122; 0123, (2014/07/22)

Disclosed is a fluorine-containing aromatic compound represented by the following general formula (1) and its production method. In the formula (1), R1 is a hydroxyl group or amino group, each of R2 to R5 is independently a hydrogen atom, or a C1-4 straight chain or a C3 or C4 branched chain alkyl group, hydrogen atoms of the alkyl group may partially or totally be replaced with fluorine atoms, n is an integer of 0 to 2, and each of m and l is independently 0 or 1. A polymer derived from this fluorine-containing aromatic compound contains —C(CF3)2OH group at a position away from the polymer main chain. Therefore, it is useful for resist use.
