84522-08-7 Usage
General Description
4-benzoylbenzene-1,2,3-triyl tris(3-diazo-3,4-dihydro-4-oxonaphthalene-1-sulphonate) is a complex organic compound commonly used as a diazo dye in the textile industry. It is synthesized by trisulfonation of 4,4'-benzoin using concentrated sulfuric acid, followed by coupling with diazonium salts of 3,4-dihydro-4-oxonaphthalene-1-sulphonic acid. The resulting compound is a deep red-orange powder with good dyeing properties, excellent light and wash fastness, and resistance to acids and alkalis. It is primarily used for dyeing cotton and other cellulosic fibers and produces bright, vibrant colors that are highly sought after in the textile market. However, it should be handled with care as it is a potential skin and eye irritant and may cause respiratory sensitization.
Check Digit Verification of cas no
The CAS Registry Mumber 84522-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,2 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84522-08:
(7*8)+(6*4)+(5*5)+(4*2)+(3*2)+(2*0)+(1*8)=127
127 % 10 = 7
So 84522-08-7 is a valid CAS Registry Number.
