Benzenediazonium, 3-sulfo-, inner salt, also known as 3-sulfobenzenediazonium or sulfanilic acid diazonium salt, is a chemical compound with the molecular formula C6H5N2O3S. It is a yellow crystalline solid that is soluble in water and is commonly used as an intermediate in the synthesis of various dyes, pigments, and pharmaceuticals. Benzenediazonium, 3-sulfo-, inner salt is formed by the diazotization of sulfanilic acid, a process that involves the reaction of sulfanilic acid with nitrous acid to form a diazonium salt. The inner salt structure of 3-sulfobenzenediazonium results from the presence of both acidic and basic functional groups within the molecule, which can undergo intramolecular proton transfer. Due to its reactivity, it is important to handle this compound with care, as it can be explosive and toxic.

618-06-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 618-06-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 618-06:
(5*6)+(4*1)+(3*8)+(2*0)+(1*6)=64
64 % 10 = 4
So 618-06-4 is a valid CAS Registry Number.
