"2-[5-(Triphenyl-λ5-phosphanylidene)-cyclopenta-1,3-dienylmethylene]-malononitrile" is a complex organic compound characterized by a unique structure. It features a cyclopenta-1,3-dienylmethylene core, which is a five-membered ring with alternating double bonds, and a malononitrile group, which consists of two cyano groups attached to a central carbon atom. The compound is further distinguished by a triphenyl-λ5-phosphanylidene moiety, where a phosphorus atom is bonded to three phenyl rings and forms a λ5-phosphanylidene bridge with the cyclopenta-1,3-dienylmethylene system. This structure contributes to the compound's stability and reactivity, making it a potentially interesting candidate for further chemical investigations and applications in various fields, such as materials science and pharmaceuticals.

1439-67-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1439-67-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1439-67:
(6*1)+(5*4)+(4*3)+(3*9)+(2*6)+(1*7)=84
84 % 10 = 4
So 1439-67-4 is a valid CAS Registry Number.
