27428-84-8 Usage
General Description
3-(Trichloromethyl)benzoyl chloride, also known as benzoyl trichloride, is an organic chemical compound with the chemical formula C8H4Cl4O. It is a colorless, oily liquid that is highly reactive and corrosive. As a benzoyl halide, it is used in organic synthesis as a reagent for the preparation of various compounds, particularly benzoyl derivatives. It is also used in the manufacture of pharmaceuticals, agrochemicals, and dyes. It is a powerful acylating agent that can react violently with water, alcohols, and amines, and should be handled and stored with extreme care due to its hazardous properties.
Check Digit Verification of cas no
The CAS Registry Mumber 27428-84-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,2 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 27428-84:
(7*2)+(6*7)+(5*4)+(4*2)+(3*8)+(2*8)+(1*4)=128
128 % 10 = 8
So 27428-84-8 is a valid CAS Registry Number.
