252291-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 252291-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,2,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 252291-80:
(8*2)+(7*5)+(6*2)+(5*2)+(4*9)+(3*1)+(2*8)+(1*0)=128
128 % 10 = 8
So 252291-80-8 is a valid CAS Registry Number.

Active yellow dye compound containing naphthalene structure and preparation method thereof

-

Paragraph 0024; 0025; 0029, (2017/08/27)

The invention discloses an active yellow dye compound containing a naphthalene structure. The structural formula of the compound is represented by the formula (I). The activity of two fluorine atoms of the compound is high, the compound can be taken as a dye with two active groups, the compound can be used to prepare a dye with a high fixation rate, and the dye does not contain any absorbable organic halogen, meets the requirements of the European AOX law, and has a good color fastness.

Active yellow-dye compound containing fluorine and preparation method thereof

-

Paragraph 0026; 0027, (2017/08/27)

The invention discloses an active yellow-dye compound containing fluorine. The structural formula of the compound is shown as a general formula (I). The active yellow-dye compound has the advantages that the activity of two fluorine atoms is also high, so that the active yellow-dye compound can be seen as a double-active-group dye, and is higher in color fixation rate; the dye does not contain absorbable organic halogen, and conforms to European AOX regulations.
