130248-64-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130248-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,4 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130248-64:
(8*1)+(7*3)+(6*0)+(5*2)+(4*4)+(3*8)+(2*6)+(1*4)=95
95 % 10 = 5
So 130248-64-5 is a valid CAS Registry Number.

Enhancement of Push–Pull Properties of Pentafulvene and Pentafulvalene Derivatives by Protonation at Carbon
, p. 739 - 749 (2018)
We report visible color changes and new intense, bathochromically shifted bands in electronic absorption spectra that reach into the near-infrared region (up to 862 nm) upon protonation of nine pentafulvene and expanded pentafulvalene derivatives. This ph
