N-Dichlorphosphinyl-(3-trifluormethyl-phenyl)-iminosulfonsaeure-chlorid, also known as N-(3-trifluoromethylphenyl)-N'-dichlorophosphoryliminosulfonic acid chloride, is a complex organophosphorus compound with the chemical formula C7H3Cl4F3NO3PS. N-Dichlorphosphinyl-(3-trifluormethyl-phenyl)-iminosulfonsaeure-chlorid is characterized by the presence of a dichloro phosphinyl group, a trifluoromethyl phenyl group, and an iminosulfonic acid chloride moiety. It is a colorless to pale yellow solid and is sensitive to moisture and heat. Due to its reactivity, it is typically used in the synthesis of various organophosphorus compounds, such as pesticides and flame retardants, and is handled with care in a controlled environment to prevent unwanted reactions.
The CAS Registry Mumber 787-89-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 7 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 787-89: (5*7)+(4*8)+(3*7)+(2*8)+(1*9)=113 113 % 10 = 3 So 787-89-3 is a valid CAS Registry Number.
