Check Digit Verification of cas no

The CAS Registry Mumber 1392438-90-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,2,4,3 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1392438-90:
(9*1)+(8*3)+(7*9)+(6*2)+(5*4)+(4*3)+(3*8)+(2*9)+(1*0)=182
182 % 10 = 2
So 1392438-90-2 is a valid CAS Registry Number.

Thermoresponsive shuttling of rotaxane containing trichloroacetate ion

Abe, Yoko,Okamura, Hisashi,Nakazono, Kazuko,Koyama, Yasuhito,Uchida, Satoshi,Takata, Toshikazu

supporting information; experimental part, p. 4122 - 4125 (2012/10/07)

A thermoresponsive rotaxane shuttling system was developed with a trichloroacetate counteranion of an ammonium/crown ether-type rotaxane. Chemoselective thermal decomposition of the ammonium trichloroacetate moiety on the rotaxane yielded the corresponding nonionic rotaxane accompanied by a positional change of the crown ether on the axle. The rotaxane skeleton facilitated effective dissociation of the acid, markedly lowering the thermal decomposition temperature.
