Nonflammable
Biochem/physiol Actions
Bacterial consortium NBNJ6 has an ability to decolorize direct red 81 (DR81).
Properties and Applications
red. Red powder. Soluble in water for product red, soluble in soluble fiber element, slightly soluble in alcohol, insoluble in other organic solvents. The strong sulfuric acid dyes for dark blue, shallow orange brown after diluted precipitation; In nitric acid solution for colourful blue, to red light brown. The dye solution to join strong hydrochloric acid for yellow olive brown precipitation; Add thick sodium hydroxide solution has the purple precipitation. 60 ℃ in the solubility of 40 g/L, not sensitive to that fights. For colourful red light. Copper ions in dyeing color slightly turn blue, encounter iron ion colored light basic unchanged. For A class SDC classification. To dead cotton cover the gender is poorer. Cotton neutral and alkaline white are level 5, viscose and minus sex of neutral white for 4 ~ 5 levels. Used for dyeing cotton and viscose, also can be used for paper color.

Check Digit Verification of cas no
The CAS Registry Mumber 2610-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,1 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2610-11:
(6*2)+(5*6)+(4*1)+(3*0)+(2*1)+(1*1)=49
49 % 10 = 9
So 2610-11-9 is a valid CAS Registry Number.
