Check Digit Verification of cas no

The CAS Registry Mumber 1628202-49-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,8,2,0 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1628202-49:
(9*1)+(8*6)+(7*2)+(6*8)+(5*2)+(4*0)+(3*2)+(2*4)+(1*9)=152
152 % 10 = 2
So 1628202-49-2 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.
