Check Digit Verification of cas no

The CAS Registry Mumber 1568337-45-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,8,3,3 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1568337-45:
(9*1)+(8*5)+(7*6)+(6*8)+(5*3)+(4*3)+(3*7)+(2*4)+(1*5)=200
200 % 10 = 0
So 1568337-45-0 is a valid CAS Registry Number.

Evaluation of hydrogen-bond acceptors for redox-switchable resorcin[4]arene cavitands

Pochorovski, Igor,Milic, Jovana,Kolarski, Dusan,Gropp, Cornelius,Schweizer, W. Bernd,Diederich, Francois

, p. 3852 - 3858 (2014)

Various H-bond acceptor groups were evaluated for their propensity to induce conformational switching between the kite and vase forms of diquinone-diquinoxaline resorcin[4]arene cavitands upon redox interconversion. The H-bond acceptors were placed on the quinoxaline walls with the purpose of stabilizing the vase form only in the reduced hydroquinone state of the cavitand by forming H-bonds with the hydroquinone OH groups. Design guidelines for successful acceptors were derived. The carboxamide acceptor was shown to be the best candidate. Based on this moiety, a redox-switchable triptycene-based basket that can completely sterically encapsulate a guest in its closed vase conformation was prepared. The basket binds small molecule guests with association constants of up to 104 M-1 in mesitylene-d12 and exhibits slow guest exchange kinetics with a half-life for guest release in the order of 104 s.
