Check Digit Verification of cas no

The CAS Registry Mumber 417699-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,7,6,9 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 417699-11:
(8*4)+(7*1)+(6*7)+(5*6)+(4*9)+(3*9)+(2*1)+(1*1)=177
177 % 10 = 7
So 417699-11-7 is a valid CAS Registry Number.

Synthetic studies of novel ninhydrin analogs

Hark, Richard R.,Hauze, Diane B.,Petrovskaia, Olga,Joullie, Madeleine M.

, p. 1632 - 1654 (2007/10/03)

Ninhydrin is an essential tool in the analysis of amino acids, peptides, and proteins, and the preferred reagent for the detection of latent fingerprints on porous surfaces. The goal of this investigation was to prepare ninhydrin analogs with enhanced chromogenic and fluorogenic properties. Target compounds included structures with extended conjugation and (or) with the presence of sulfur-containing moieties. We have devised general convergent routes for novel heterocyclic and aryl-substituted ninhydrin analogs for use as reagents for amino acid detection.
