Check Digit Verification of cas no

The CAS Registry Mumber 260358-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,3,5 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 260358-03:
(8*2)+(7*6)+(6*0)+(5*3)+(4*5)+(3*8)+(2*0)+(1*3)=120
120 % 10 = 0
So 260358-03-0 is a valid CAS Registry Number.

New irreversible thermochromic polydiacetylenes

Rougeau, Laurent,Picq, Dominique,Rastello, Marie,Frantz, Yves

, p. 9430 - 9436 (2008)

New diacetylenic compounds are described. These compounds are unfunctionalised, monoalcohols, diols or monoesters and present irreversible thermochromic behaviour. When heated, these diynes change colour from blue to red in temperature ranging between -50 and +75 °C depending on chain lengths. A relationship between the number of atoms and the thermochromism temperature has been highlighted. Moreover, a mechanism of this thermochromic phenomenon is demonstrated based on Raman spectroscopy, ESR and solid NMR.
