Benzene-diazonium-2-carboxylate, also known as benzene-1-diazonium-2-carboxylate, is an organic compound with the chemical formula C7H5N2O2. It is a derivative of benzoic acid, where the hydroxyl group (-OH) is replaced by a diazonium group (-N2+). benzene-diazonium-2-carboxylate is a key intermediate in the synthesis of various dyes, pharmaceuticals, and other organic compounds. It is typically prepared through the diazotization of 2-aminobenzoic acid, a process that involves the reaction of the amino group with nitrous acid to form the diazonium ion. Benzene-diazonium-2-carboxylate is a white crystalline solid that is sensitive to light and heat, and it is commonly used in chemical reactions as a source of the diazonium ion for coupling with other molecules.

1608-42-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1608-42-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1608-42:
(6*1)+(5*6)+(4*0)+(3*8)+(2*4)+(1*2)=70
70 % 10 = 0
So 1608-42-0 is a valid CAS Registry Number.
