30736-15-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 30736-15-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,7,3 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 30736-15:
(7*3)+(6*0)+(5*7)+(4*3)+(3*6)+(2*1)+(1*5)=93
93 % 10 = 3
So 30736-15-3 is a valid CAS Registry Number.

Untersuchungen zur Chemie von Isoindolen und Isoindoleninen, XXXVIII. 3-Alkoxy-1H-isoindole mit Substituenten am 5-Ring - Heterocycliche Imidsaeureester mit fixierter benzoider Struktur.

Kreher, Richard P.,Hennige, Hans,Konrad, Michael,Uhrig, Juergen,Clemens, Andrea

, p. 809 - 828 (2007/10/02)

3-Alkoxy-1H-isoindoles bearing substituents at the five-membered ring have been synthesized starting with substituted isoindoline-1-ones via regiospecific O-alkylation with trialkyl oxonium tetrafluoroborates or alkyl trifluoromethanesulfonates and subsequent NH-deprotonation.The dependence of spectroscopic properties on the substituents has been investigated.The heterocyclic imidates exist exclusively in the benzenoid 1H-structure; the tautomeric o-quinonoid 2H-form cannot be detected by spectroscopic means.
