Check Digit Verification of cas no

The CAS Registry Mumber 22157-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22157-90:
(7*2)+(6*2)+(5*1)+(4*5)+(3*7)+(2*9)+(1*0)=90
90 % 10 = 0
So 22157-90-0 is a valid CAS Registry Number.

Anion binding versus intramolecular hydrogen bonding in neutral macrocyclic amides

Chmielewski, Michal J.,Jurczak, Janusz

, p. 7652 - 7667 (2006)

Although amide groups are important hydrogen-bond donors in natural and synthetic anion receptors, studies on structure-affinity relationships of amide-based macrocyclic receptors are still very limited. Therefore, we synthesized a series of macrocyclic t

A rigid sublimable naphthalenediimide cyclophane as model compound for UHV STM experiments

Gabutti, Sandro,Knutzen, Marco,Neuburger, Markus,Schull, Guillaume,Berndt, Richard,Mayor, Marcel

supporting information; experimental part, p. 2370 - 2372 (2009/02/03)

The design, synthesis and characterization of a rigid naphthalenediimide cyclophane as a model compound for ultrahigh vacuum (UHV) STM experiments are described together with first self-assembly investigations on an Au(111) substrate displaying the format

Novel self-assembly of m-xylylene type dithioureas by head-to-tail hydrogen bonding

Tobe, Yoshito,Sasaki, Shin-Ichi,Mizuno, Masaaki,Hirose, Keiji,Naemura, Koichiro

, p. 7481 - 7489 (2007/10/03)

Dithiourea la self-assembles to form an orthogonal dimer structure both in solution and in the solid state, wherein the four thiourea groups establish a closed network of hydrogen bonds through a head-to-tail binding mode. This novel dimer structure was elucidated on the basis of 1H NMR spectra, vapor pressure osmometry, and X-ray crystal structure analysis. Furthermore, a series of m-xylylene type dithioureas were synthesized and their dimerization constants (Ka) in CDCl3 were determined by dilution experiments using 1H NMR spectroscopy. The magnitude of the Ka values are dependent on the steric bulk of the side chains, the acidity of the thiourea groups, and the weak intermolecular interaction between the benzene rings of the side chains and the m-xylylene spacer.
