Check Digit Verification of cas no

The CAS Registry Mumber 193408-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,4,0 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 193408-02:
(8*1)+(7*9)+(6*3)+(5*4)+(4*0)+(3*8)+(2*0)+(1*2)=135
135 % 10 = 5
So 193408-02-5 is a valid CAS Registry Number.

Synthesis and characterization of stilbene derivatives for possible incorporation as smart additives in polymers used as packaging films

Day, Gary M.,Howell, Owen T.,Metzler, Michael R.,Woodgate, Paul D.

, p. 425 - 434 (2007/10/03)

Several series of stilbene derivatives for possible use as smart additives in polymers used as packaging films have been prepared and characterized. Differential scanning calorimetry was performed on some of the stilbenes in order to determine any liquid crystal properties. Those compounds which had multiple phase transitions were also shown to have two liquid crystalline phases according to optical microscopy.
