1440420-07-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1440420-07-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,4,2 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1440420-07:
(9*1)+(8*4)+(7*4)+(6*0)+(5*4)+(4*2)+(3*0)+(2*0)+(1*7)=104
104 % 10 = 4
So 1440420-07-4 is a valid CAS Registry Number.

Mono-functionalized dibenzo[g,p]-chrysenes for cascade energy transfer
Heyer, Elodie,Ziessel, Raymond
, p. 3388 - 3393 (2013/07/19)
3-Bromodibenzo[g,p]chrysene has been synthesized in a one-pot reaction using phenyliodine(III) bis(trifluoroacetate) (PIFA) as an oxidant and a Lewis acid. The bromo function was easily converted to the cyano, alkyne, and formyl derivatives. Bodipy dyes h
