Check Digit Verification of cas no

The CAS Registry Mumber 887768-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,7,6 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 887768-87:
(8*8)+(7*8)+(6*7)+(5*7)+(4*6)+(3*8)+(2*8)+(1*7)=268
268 % 10 = 8
So 887768-87-8 is a valid CAS Registry Number.

Synthesis and1H-NMR characterization of the self-assembly based on melamine - 5,5′-diethylbarbituric acid

Pokrop,Lipkowski,Jurczak

, p. 893 - 901 (2008/09/17)

This paper describes the results of systematic studies of various parameters which are responsible for the hydrogen-bond stabilization of self-assemblies based on melamine and 5,5′-diethylbarbituric acid. The 1:1 self-assembly is exemplified by eight supr

Self-assembly of a [2 x 2] hydrogen bonded grid

Lipkowski, Piotr,Bielejewska, Anna,Kooijman, Huub,Spek, Anthony L.,Timmerman, Peter,Reinhoudt, David N.

, p. 1311 - 1312 (2007/10/03)

Formation of 24 cooperative hydrogen bonds drives the spontaneous assembly of a rigid bifunctional trimelamine and bis(barbituric acid) to give selectively the [2 x 2] hydrogen-bonded grid, in preference to the corresponding [1 x 1] or polymeric assemblie
