General Description
(4-methylphenyl)phosphonic dichloride is a chemical compound with the molecular formula C7H8Cl2OP. It is a phosphorus-based compound that consists of a phosphonic acid group and two chlorine atoms attached to a 4-methylphenyl (also known as para-tolyl) group. (4-methylphenyl)phosphonic dichloride exhibits reactivity typical of an acyl chloride, making it a useful reagent in organic synthesis for the introduction of phosphonate groups into various molecules. Additionally, (4-methylphenyl)phosphonic dichloride can be used as a precursor in the synthesis of phosphonate esters, which have applications in pharmaceuticals, agrochemicals, and materials science. However, it is important to handle this compound with caution, as it can be corrosive and may release toxic fumes when exposed to water or moisture.
Check Digit Verification of cas no
The CAS Registry Mumber 17566-84-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,6 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17566-84:
(7*1)+(6*7)+(5*5)+(4*6)+(3*6)+(2*8)+(1*4)=136
136 % 10 = 6
So 17566-84-6 is a valid CAS Registry Number.
