904930-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 904930-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,9,3 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 904930-18:
(8*9)+(7*0)+(6*4)+(5*9)+(4*3)+(3*0)+(2*1)+(1*8)=163
163 % 10 = 3
So 904930-18-3 is a valid CAS Registry Number.

Dynamic covalently bonded rotaxanes cross-linked by imine bonds between the axle and ring: Inverse temperature dependence of subunit mobility

Kawai, Hidetoshi,Umehara, Takeshi,Fujiwara, Kenshu,Tsuji, Takashi,Suzuki, Takanori

, p. 4281 - 4286 (2006)

(Figure Presented) Building bridges: Imine bridges between the axle and ring components in rotaxanes allow simple rotaxane synthesis and a novel method for motion control to be developed. The submolecular mobility in this rotaxane-type assembly is regulated by the imine-bond formation/cleavage (see scheme). The relative abundance of the [2]rotaxane increases with decreasing temperature under dynamic equilibrium conditions.
