Phenylmethanesulfonic acid, also known as benzylsulfonic acid, is an organic compound with the chemical formula C7H8O3S. It is a colorless crystalline solid that is soluble in water and has a strong, pungent odor. The sodium salt of phenylmethanesulfonic acid is formed when the acid reacts with sodium hydroxide, resulting in the chemical formula C7H7NaO3S. This sodium salt is a white crystalline solid that is also soluble in water. Both the acid and its sodium salt are used in various industrial applications, such as in the synthesis of dyes, pharmaceuticals, and as intermediates in organic chemistry. They are also used as catalysts and reagents in chemical reactions. Due to their reactivity and potential hazards, they must be handled with care and used in accordance with safety guidelines.

7494-46-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7494-46-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.Calculate Digit Verification of CAS Registry Number 7494-46:
(6*7)+(5*4)+(4*9)+(3*4)+(2*4)+(1*6)=124
124 % 10 = 4
So 7494-46-4 is a valid CAS Registry Number.
