Check Digit Verification of cas no
The CAS Registry Mumber 118951-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,5 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118951-68:
(8*1)+(7*1)+(6*8)+(5*9)+(4*5)+(3*1)+(2*6)+(1*8)=151
151 % 10 = 1
So 118951-68-1 is a valid CAS Registry Number.

Synthesis, Photochromism, and Thermal Stability of Two New Diarylethenes Based On Spirobifluorene
Li, Caihua,Zeng, Heping
, p. 1706 - 1714 (2016)
Two novel spirobifluorene-diarylethenes compounds with furan (9a) and thiophen (8a) as heterocyclic aryl groups were successfully synthesized, and their structures were fully characterized with FTIR, NMR, mass spectra (MS), and elemental analysis. Their photochromic properties were examined. The results indicated that they showed good photochromic behaviors in hexane and acetonitrile. The fluorescence emission was quenched along with the photochromism from open ring to closed ring. Large fluorescence emission blue-shift was clearly observed in polar solvents. Furthermore, the thermal stability of 8a and 9a was greatly improved by introducing spirobifluorene group into the molecules. The 5% loss weight temperature of 9a was 59°C higher than that of 10a without spirobifluorene.
