1240575-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240575-49-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,7 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1240575-49:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*7)+(3*5)+(2*4)+(1*9)=138
138 % 10 = 8
So 1240575-49-8 is a valid CAS Registry Number.

Dithienophosphole-capped π-conjugated oligomers
Durben, Stefan,Linder, Thomas,Baumgartner, Thomas
, p. 1585 - 1592 (2010/10/03)
The synthesis of a 2-monobrominated dithieno[3,2-b:2′,3′-d] phosphole has opened the access to a series of highly luminescent π-conjugated oligomers that link two dithienophosphole units via a variety of aromatic spacers. The nature of the linking mode wa
