Phthalimide sulfonic acid chloride is a chemical compound with the molecular formula C8H4ClNO4S. It is derived from phthalimide, a heterocyclic organic compound, by the substitution of a hydroxyl group with a sulfonic acid group and a chlorine atom. phthalimide sulfonic acid chloride is an important intermediate in the synthesis of various pharmaceuticals, dyes, and other organic compounds. It is known for its reactivity, particularly in nucleophilic substitution reactions, and is used in the preparation of sulfonamide drugs and other sulfur-containing compounds. The compound is typically synthesized through the chlorosulfonation of phthalimide, a process that introduces both the sulfonic acid and the acid chloride functionalities. Due to its reactivity, it is often used in the formation of sulfonamide linkages in pharmaceuticals, contributing to the development of new drugs with improved properties.

Check Digit Verification of cas no

The CAS Registry Mumber 3481-04-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,8 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3481-04:
(6*3)+(5*4)+(4*8)+(3*1)+(2*0)+(1*4)=77
77 % 10 = 7
So 3481-04-7 is a valid CAS Registry Number.
