Check Digit Verification of cas no

The CAS Registry Mumber 426823-96-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,6,8,2 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 426823-96:
(8*4)+(7*2)+(6*6)+(5*8)+(4*2)+(3*3)+(2*9)+(1*6)=163
163 % 10 = 3
So 426823-96-3 is a valid CAS Registry Number.

A new method for the synthesis of N-substituted (4-oxo-4,5,6,7-tetrahydroindol-3-yl)acetic acids

Dudinov,Kozhinov,Krayushkin

, p. 1259 - 1263 (2007/10/03)

A new method for the synthesis of N-substituted 2-(4-oxo-4,5,6,7-tetrahydroindol-3-yl)acetic acids was developed. Alkylation of cyclic 1,3-diketones with 3,5,5,5-tetrachloropentan-2-one affords 1,4-diketones, which undergo cyclization with different primary amines into N-substituted 3-(2,2,2-trichloroethyl)-4,5,6,7-tetrahydroindol-4-ones. Acid hydrolysis of the latter gives the corresponding indol-3-ylacetic acids. The structures of the compounds obtained were confirmed by 1H and 13C NMR data.
