Benzenemethanediazonium chloride, also known as benzenediazonium chloride or benzenediazonium chloride salt, is a chemical compound with the formula C7H7N2+Cl-. It is a white crystalline solid that is highly soluble in water and serves as a key intermediate in the synthesis of various organic compounds, particularly in the preparation of aryl diazonium salts. These salts are widely used in the chemical industry for the production of dyes, pigments, and pharmaceuticals. Benzenemethanediazonium chloride is also employed in the Sandmeyer reaction, which allows for the conversion of aryl diazonium salts into aryl halides, and in the diazotization process, where it plays a crucial role in the formation of diazonium compounds. Due to its reactivity and potential to form explosive diazonium salts, it requires careful handling and storage.

90740-03-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90740-03-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,4 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90740-03:
(7*9)+(6*0)+(5*7)+(4*4)+(3*0)+(2*0)+(1*3)=117
117 % 10 = 7
So 90740-03-7 is a valid CAS Registry Number.
