197152-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197152-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,5 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 197152-18:
(8*1)+(7*9)+(6*7)+(5*1)+(4*5)+(3*2)+(2*1)+(1*8)=154
154 % 10 = 4
So 197152-18-4 is a valid CAS Registry Number.

Synthesis of sulfone-substituted furan chromophores with high molecular hyperppolarizability
Chou, Shang-Shing P.,Shen, Chih-Hung
, p. 6407 - 6410 (2007/10/03)
A series of sulfone-substituted furan chromophores were synthesized which showed high molecular hyperpolarizabilities as measured by solvatochromism, and good transparency in the visible region.
