1604-42-8 Usage
General Description
1,6-dinitroanthraquinone is a chemical compound that belongs to the family of anthraquinones. It is commonly used as a yellow dye in the textile industry, as well as in the production of colored wood stains and printing inks. It is also known for its use as an intermediate in the synthesis of pharmaceuticals and agrochemicals. 1,6-dinitroanthraquinone is a crystalline solid with a bright yellow color, and it is soluble in organic solvents such as acetone and ethanol. It is important to handle this compound with care, as it is classified as a hazardous chemical due to its toxicity and potential to cause skin irritation and respiratory problems if inhaled. Additionally, it is important to avoid exposure to sunlight, as 1,6-dinitroanthraquinone is sensitive to light and can decompose when exposed to UV radiation.
Check Digit Verification of cas no
The CAS Registry Mumber 1604-42-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1604-42:
(6*1)+(5*6)+(4*0)+(3*4)+(2*4)+(1*2)=58
58 % 10 = 8
So 1604-42-8 is a valid CAS Registry Number.
