Check Digit Verification of cas no

The CAS Registry Mumber 1021465-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,4,6 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1021465-71:
(9*1)+(8*0)+(7*2)+(6*1)+(5*4)+(4*6)+(3*5)+(2*7)+(1*1)=103
103 % 10 = 3
So 1021465-71-3 is a valid CAS Registry Number.

(Chemical Equation Presented) A room-temperature light-driven molecular brake (1), consisting of a pentiptycene rotator, a 3,5-dinitrophenyl brake, and a photoisomerizable ethenyl spacer, is reported. The rotation rates of the rotator differ by about 9 orders of magnitude between the brake-on (cis-1) and brake-off (trans-1) states.

Pentiptycene-derived light-driven molecular brakes: Substituent effects of the brake component

experimental part, p. 11594 - 11604 (2010/12/18)

Five pentiptycene-derived stilbene systems (1R; R = H, OM, NO, Pr, and Bu) have been prepared and investigated as light-driven molecular brakes that have different-sized brake components (1Hrot = 108-109 s-1) with little interaction with the brake component in the trans form ((E)-1R), which corresponds to the brake-off state. When the brake is turned on by photoisomerization to the cis form ((Z)-1R), the pentiptycene rotation can be arrested on the NMR spectroscopic timescale at temperatures that depend on the brake component. In the cases of (Z)-1NO, (Z)-1Pr, and (Z)-1Bu, the rotation is nearly blocked (krot = 2-6 s-1) at 298 K. It is also demonstrated that the rotation is slower in [D6]DMSO than in CD2Cl 2. A linear relationship between the free energies of the rotational barrier and the steric parameter A values is present only for (Z)-1H, (Z)-1OM, and (Z)-1NO, and it levels off on going from (Z)-1NO to (Z)-1Pr and (Z)-1Bu. DFT calculations provide insights into the substituent effects in the rotational ground and transition states. The molar reversibility of the E-Z photoswitching is up to 46%, and both the E and Z isomers are stable under the irradiation conditions.
