Check Digit Verification of cas no

The CAS Registry Mumber 124615-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,1 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124615-98:
(8*1)+(7*2)+(6*4)+(5*6)+(4*1)+(3*5)+(2*9)+(1*8)=121
121 % 10 = 1
So 124615-98-1 is a valid CAS Registry Number.

The design and synthesis of a series of pyrrolo[2,1-c][1,4]benzodiazepine (PBD)- polyaminoalkyl conjugates as DNA minor groove binders are described. To introduce polyaminoalkyl groups to the pyrrolo[2,1-c][1,4]benzodiazepine pharmacophore, SNA

Multi-layer macromonocyclic polyamines. I. Molecular design and synthesis of component monocyclic precursors

Iwata, Masaaki

, p. 693 - 704 (2007/10/03)

We designed 'multi-layer macromonocyclic polyamines' which might be appropriate polymorphismic molecular scaffolds as host-molecules in ionic or molecular interaction with small or large guest ions or molecules. In polymorphismic molecules, several macromonocyclic polyamines with the same and/or different ring sizes and nitrogen contents are connected to each other by alkylene spacers with various length of the chain. Actual target molecules are characterized by possessing methylene chain arrays of natural polyamines, and we have synthesized from simple starting materials fourteen component macromonocycles with various sizes, 12- to 34-membered rings containing three to eight nitrogen atoms, as essential building blocks required for construction of multi-layer molecules. Our method of synthesis was shown to be very efficient. In a final step, the N-protecting benzyl group was successfully removed by hydrogenation on 10%-Pd/C under 4 kg cm-2 H2 to give the cyclic amine precursors, which could be internal and terminal components in the architecture of the multi-layer molecules. The structures of synthesized compounds were characterized and confirmed by EA, 1H NMR, SIMS, and FAB(+) mass spectrometry.
