2641-89-6 Usage
General Description
Tetrabromohydroquinone is a chemical compound consisting of a hydroquinone molecule with four bromine atoms attached to it. It is mainly used as a flame retardant, particularly in plastics and epoxy resins. Tetrabromohydroquinone has the ability to suppress the combustion process by releasing bromine radicals when exposed to heat, thus preventing or slowing down the spread of fire. It is also used as an intermediate in the production of other flame retardants and as a stabilizer in rubber and plastic manufacturing. However, it is important to handle tetrabromohydroquinone with caution, as it is considered toxic and may have harmful effects on human health and the environment if not properly managed and disposed of.
Check Digit Verification of cas no
The CAS Registry Mumber 2641-89-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2641-89:
(6*2)+(5*6)+(4*4)+(3*1)+(2*8)+(1*9)=86
86 % 10 = 6
So 2641-89-6 is a valid CAS Registry Number.
