N-Dichlorphosphinyl-phenyliminosulfonsaeure-chlorid, also known as N-dichlorophosphinyl-phenyliminosulfonyl chloride, is a complex organophosphorus compound with the chemical formula C6H4Cl3NO2PS. N-Dichlorphosphinyl-phenyliminosulfonsaeure-chlorid is characterized by the presence of a phenyl group (C6H5), a dichlorophosphinyl group (PCl2), and an iminosulfonyl chloride group (N=S(O)Cl). It is a colorless to pale yellow solid and is sensitive to moisture and heat. Due to its reactivity, it is typically used as an intermediate in the synthesis of various organophosphorus compounds, such as pesticides and pharmaceuticals. The compound's reactivity arises from the presence of the electrophilic iminosulfonyl chloride group, which can readily react with nucleophiles in chemical transformations. It is important to handle N-Dichlorphosphinyl-phenyliminosulfonsaeure-chlorid with care due to its potential toxicity and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 4424-04-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4424-04:
(6*4)+(5*4)+(4*2)+(3*4)+(2*0)+(1*4)=68
68 % 10 = 8
So 4424-04-8 is a valid CAS Registry Number.
