"Ph2PC*C-C*CPh" is a complex organic molecule with a unique structure. It consists of two phenyl groups (Ph), a phosphorus atom (P), and two carbon-carbon triple bonds (C*C). The molecule is characterized by its conjugated system, which extends from one phenyl group through the phosphorus atom and the two triple bonds to the other phenyl group. This conjugation can influence the molecule's electronic properties, such as its reactivity and stability. The presence of phosphorus introduces a heteroatom into the molecule, which can affect its polarity and potentially its coordination chemistry. The molecule's structure suggests it may have interesting photophysical or electronic properties, making it a subject of interest in organic chemistry and materials science.

7608-31-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7608-31-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,0 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7608-31:
(6*7)+(5*6)+(4*0)+(3*8)+(2*3)+(1*1)=103
103 % 10 = 3
So 7608-31-3 is a valid CAS Registry Number.
