4-Nitro-1-(4-methoxy-phenyl)-buten-2-on-1, also known as 4-nitro-1-(4-methoxyphenyl)-2-buten-1-one, is an organic compound characterized by a 2-buten-1-one backbone with a nitro group at the 4-position and a 4-methoxyphenyl group attached to the 1-position. This molecule features a conjugated system due to the presence of the nitro group and the double bond, which can influence its reactivity and electronic properties. The 4-methoxy group provides additional electron-donating character through resonance, potentially affecting the molecule's stability and reactivity. 4-Nitro-1-(4-methoxy-phenyl)-buten-⁽²⁾-on-⁽¹⁾ may be of interest in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 4994-92-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4994-92:
(6*4)+(5*9)+(4*9)+(3*4)+(2*9)+(1*2)=137
137 % 10 = 7
So 4994-92-7 is a valid CAS Registry Number.
