Formohydroxamic acid, also known as N-formylhydroxylamine or formyhydroxylamine, is an organic compound with the chemical formula HON=CHO. It is a colorless, unstable, and highly reactive molecule that is formed as an intermediate in various chemical reactions, such as the oxidation of hydroxylamine. Formohydroxamic acid plays a significant role in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Due to its instability, it is often generated in situ and used immediately in subsequent reactions. It is also known for its potential applications in the detection of metal ions, particularly in analytical chemistry.
The CAS Registry Mumber 4167-98-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,6 and 7 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4167-98: (6*4)+(5*1)+(4*6)+(3*7)+(2*9)+(1*8)=100 100 % 10 = 0 So 4167-98-0 is a valid CAS Registry Number.
