(E)-2(3-(4-nitrophenyl)allylidene)malononitrile is a synthetic organic compound characterized by its vibrant yellow color. It is a member of the azo dye family, which are known for their strong color properties and are widely used in the textile, food, and pharmaceutical industries. This particular compound is formed by the condensation of malononitrile with 4-nitrobenzaldehyde, resulting in a molecule with a distinctive structure that includes a nitro group attached to a phenyl ring, which is further connected to a conjugated system of double bonds and a cyano group. The compound's chemical formula is C12H6N4O2, and its molecular weight is 238.21 g/mol. It is important to note that due to the presence of the nitro group, (E)-2(3-(4-nitrophenyl)allylidene)malononitrile may have potential explosive properties and should be handled with caution.

Check Digit Verification of cas no

The CAS Registry Mumber 66684-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,8 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66684-76:
(7*6)+(6*6)+(5*6)+(4*8)+(3*4)+(2*7)+(1*6)=172
172 % 10 = 2
So 66684-76-2 is a valid CAS Registry Number.
