Phthaloyl bromide, also known as 1,2-dibromobenzene, is an organic compound with the chemical formula C6H4Br2. It is a colorless, crystalline solid that is soluble in organic solvents. Phthaloyl bromide is primarily used as a chemical intermediate in the synthesis of various dyes, pharmaceuticals, and other organic compounds. It is produced through the bromination of phthalic anhydride or by the direct bromination of benzene. Due to its reactivity, it is important to handle phthaloyl bromide with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.
The CAS Registry Mumber 877-23-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 7 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 877-23: (5*8)+(4*7)+(3*7)+(2*2)+(1*3)=96 96 % 10 = 6 So 877-23-6 is a valid CAS Registry Number.
