Naphthalene-2-sulfonyl iodide, also known as 2-naphthalenesulfonyl chloride or 2-NSI, is a chemical compound with the molecular formula C10H7ClO2S. It is a white crystalline solid that is soluble in organic solvents such as ethanol, acetone, and dichloromethane. naphthalene-2-sulfonyl iodide is primarily used as a reagent in organic synthesis, particularly for the preparation of various sulfonamide derivatives and as a protecting group in peptide synthesis. It is also employed in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, it is important to handle 2-NSI with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

1950-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1950-79-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,5 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.Calculate Digit Verification of CAS Registry Number 1950-79:
(6*1)+(5*9)+(4*5)+(3*0)+(2*7)+(1*9)=94
94 % 10 = 4
So 1950-79-4 is a valid CAS Registry Number.
