57296-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57296-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,9 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57296-02:
(7*5)+(6*7)+(5*2)+(4*9)+(3*6)+(2*0)+(1*2)=143
143 % 10 = 3
So 57296-02-3 is a valid CAS Registry Number.

Synthesis and spectral properties of malononitrile-based merocyanine dyes
Kulinich,Derevyanko,Ishchenko
, p. 2820 - 2830 (2007/10/03)
Di-, tetra-, and hexamethine merocyanines derived from malononitrile and heterocycles with moderate (dyes 1-6), strong (7-9), and weak (10 and 11) electron-releasing ability were synthesized. The electronic structures of merocyanines 10 and 11 are similar
