87437-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87437-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,3 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87437-12:
(7*8)+(6*7)+(5*4)+(4*3)+(3*7)+(2*1)+(1*2)=155
155 % 10 = 5
So 87437-12-5 is a valid CAS Registry Number.

2,6-diphospha-s-indacene-1,3,5,7(2H,6H)-tetraone: A phosphorus analogue of aromatic diimides with the minimal core exhibiting high electron-accepting ability

Takeda, Youhei,Nishida, Takuya,Minakata, Satoshi

supporting information, p. 10266 - 10270 (2014/08/18)

Phosphorus analogues of pyrromellitic diimides (PyDIs), which represent a family of privileged electron-accepting organic compounds, have been successfully synthesized as novel electron-accepting π-conjugated molecules. Investigation into their physicochemical properties uncovered their prominent electron-accepting abilities over the corresponding PyDI. Furthermore, theoretical studies revealed the significant contribution of σ*-π* hyperconjugation in stabilizing the LUMO+1.
