Phenylazo-i-butyric acid nitrile, also known as 2-(4-nitrophenylazo)-2-methylpropionitrile, is an organic compound with the chemical formula C10H10N4O2. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and acetone. phenylazo-i-butyric acid nitrile is primarily used as a chemical intermediate in the synthesis of various dyes and pigments, particularly those with azo groups. Due to its reactivity and the presence of nitro and cyano functional groups, it is important to handle phenylazo-i-butyric acid nitrile with care, as it may pose health and environmental risks.

Check Digit Verification of cas no

The CAS Registry Mumber 1825-33-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1825-33:
(6*1)+(5*8)+(4*2)+(3*5)+(2*3)+(1*3)=78
78 % 10 = 8
So 1825-33-8 is a valid CAS Registry Number.

Electrochemical formation of methoxy- and cyano(phenylazo)alkanes from aldehyde and ketone phenylhydrazones

Okimoto, Mitsuhiro,Takahashi, Yukio,Kakuchi, Toyoji

, p. 2057 - 2063 (2003)

Several aldehyde and ketone phenylhydrazones were electrooxidized in MeOH. Electrooxidation in the presence of KI or tetraethylammonium p-toluenesulfonate as the supporting electrolyte afforded the corresponding methoxy(phenylazo)alkanes, whereas electrooxidation in the presence of KI, NaCN, and HOAc afforded the cyano(phenylazo)alkanes.
