1268470-44-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268470-44-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,4,7 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1268470-44:
(9*1)+(8*2)+(7*6)+(6*8)+(5*4)+(4*7)+(3*0)+(2*4)+(1*4)=175
175 % 10 = 5
So 1268470-44-5 is a valid CAS Registry Number.

Push-pull aminobithiophenes - Highly fluorescent stable fluorophores
Dong, Yanmei,Bolduc, Andreanne,McGregor, Nicholas,Skene
, p. 1844 - 1847 (2011)
Stable 2-aminobithiophenes were prepared using the Gewald reaction. The resulting push-pull bithiophenes exhibited both unprecedented high fluorescence yields and stability in addition to demonstrating fluorescence on-off properties.
