3-Phenylazo-crotononitrile, also known as 3-(phenylazo)-2-butenenitrile, is an organic compound with the chemical formula C10H8N2. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and acetone. 3-phenylazo-crotononitrile is characterized by the presence of a phenylazo group (-N=N-Ph) attached to a crotononitrile moiety, which consists of a conjugated double bond system and a nitrile group (-CN). 3-Phenylazo-crotononitrile is synthesized through the coupling of phenylhydrazine with crotononitrile in the presence of a coupling agent, such as diazonium salts. It is used as a chemical intermediate in the synthesis of various dyes, pigments, and other organic compounds. Due to its reactive nature, it is important to handle 3-phenylazo-crotononitrile with care, as it may pose health risks and environmental concerns.

Check Digit Verification of cas no

The CAS Registry Mumber 538-54-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 538-54:
(5*5)+(4*3)+(3*8)+(2*5)+(1*4)=75
75 % 10 = 5
So 538-54-5 is a valid CAS Registry Number.
