Cyanoglyoxylsaeure-4-chlorphenylhydrazon, also known as 4-chlorophenylhydrazone of cyanoglyoxylic acid, is a chemical compound with the molecular formula C8H5ClN4O2. It is formed by the reaction of cyanoglyoxylic acid with 4-chlorophenylhydrazine, resulting in a derivative that exhibits a strong affinity for metal ions, particularly copper. This property makes it useful in analytical chemistry for the detection and quantification of copper in various samples. The compound is typically employed in colorimetric assays, where the color change upon binding with copper ions can be measured to determine the concentration of the metal. Its chemical structure and reactivity also make it a subject of interest in the field of coordination chemistry, where it can form complexes with metal ions, providing insights into the nature of metal-ligand interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 3846-44-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,4 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3846-44:
(6*3)+(5*8)+(4*4)+(3*6)+(2*4)+(1*4)=104
104 % 10 = 4
So 3846-44-4 is a valid CAS Registry Number.
