339267-17-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 339267-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,9,2,6 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 339267-17:
(8*3)+(7*3)+(6*9)+(5*2)+(4*6)+(3*7)+(2*1)+(1*7)=163
163 % 10 = 3
So 339267-17-3 is a valid CAS Registry Number.

, p. 523 - 528 (2007/10/03)

The synthesis of triphaeridine and norchelerythrine through palladium-catalyzed aryl-aryl coupling reactions was studied. The secondary amides were synthesized from 6-bromopiperonylicacid and aniline, and from piperonylic acid and 2-iodoaniline respectively, and were methoxymethylated for the preparation of starting materials for the cyclization reaction. All experiments were carried out in an argon atmosphere and the extract was washed with brine. The nuclear magnetic resonance (NMR) spectral data showed the presence of singlet signals due to aromatic proton in the products.
