4-phenylhydrazono-cis-crotonic acid is an organic compound with the molecular formula C10H12N2O2. It is a derivative of crotonic acid, featuring a phenylhydrazone functional group attached to the double bond. 4-phenylhydrazono-cis-crotonic acid is characterized by its ability to form a stable chelate with metal ions, making it useful in analytical chemistry for the detection and quantification of certain metals. The cis-isomer specifically refers to the geometric arrangement of the double bond, where the phenyl and carboxylic acid groups are on the same side of the molecule. This geometric isomerism can significantly affect the compound's chemical properties and reactivity. The compound is typically synthesized through the reaction of crotonic acid with phenylhydrazine, and it is often used in the qualitative analysis of metals due to its formation of colored complexes.

Check Digit Verification of cas no

The CAS Registry Mumber 3193-97-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3193-97:
(6*3)+(5*1)+(4*9)+(3*3)+(2*9)+(1*7)=93
93 % 10 = 3
So 3193-97-3 is a valid CAS Registry Number.
