Check Digit Verification of cas no

The CAS Registry Mumber 643-38-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 643-38:
(5*6)+(4*4)+(3*3)+(2*3)+(1*8)=69
69 % 10 = 9
So 643-38-9 is a valid CAS Registry Number.

Method for preparing nitrogen-containing six-membered ring dicarboxylic acid

-

Paragraph 0048-0050; 0052, (2020/04/22)

The invention relates to compound preparation, particularly to a method for preparing nitrogen-containing six-membered ring dicarboxylic acid from a benzo nitrogen-containing six-membered ring compound. According to the method, a raw material compound and a sodium chlorate aqueous solution are catalyzed under an acidic condition to obtain nitrogen-containing six-membered ring dicarboxylic acid, wherein the raw material is a nitrogen-containing six-membered heterocyclic benzocyclic compound. According to the invention, the catalyst of the reaction system is low in toxicity and low in cost, no new impurity is generated in the post-treatment step, and large-scale production is facilitated.

New efficient access to fused (Het)Aryltetrahydroindolizinones via N-acyl iminium intermediates

Chiurato, Matteo,Boulahjar, Rajaa,Routier, Sylvain,Troin, Yves,Guillaumet, Gérald

scheme or table, p. 4647 - 4653 (2010/07/05)

In this paper, we described the preparation of fused (Het)Aryltetrahydroindolizinones via N-acyl iminium intermediates. Two different routes were also explored to achieve the synthesis. The first one consists in the intramolecular reaction of β-hydroxylactams whereas the second route one is an intermolecular condensation between a 2-formylester or a β-alkoxylactone and an appropriate primary amine. We also developed two heterocyclic strategies to obtain the adequate unavailable starting materials in pyridine, pyrazine, quinoline, and quinaxoline series and then perform all inter or intramolecular reactions. Scope and limitations are given.
