928047-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928047-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,0,4 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 928047-98:
(8*9)+(7*2)+(6*8)+(5*0)+(4*4)+(3*7)+(2*9)+(1*8)=197
197 % 10 = 7
So 928047-98-7 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
