900027-21-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 900027-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,0,2 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 900027-21:
(8*9)+(7*0)+(6*0)+(5*0)+(4*2)+(3*7)+(2*2)+(1*1)=106
106 % 10 = 6
So 900027-21-6 is a valid CAS Registry Number.

Preparation of polyfunctional aryl azides from aryl triazenes. A new synthesis of ellipticine, 9-methoxyellipticine, isoellipticine, and 7-carbethoxyisoellipticine

Liu, Ching-Yuan,Knochel, Paul

, p. 7106 - 7115 (2008/02/11)

(Chemical Equation Presented) The preparation of polyfunctional aryl azides by the reaction of aryl triazenes with NaN3 in the presence of KHSO4 or BF3·OEt2/TFA (trifluoroacetic acid) has been described. A variety of functional groups (halides, esters, ketones, nitriles, aldehydes, and boronic esters) are tolerated under the Lewis acidic conditions. By using this methodology, the potent antitumor agents, ellipticine and 9-methoxyellipticine, have been synthesized. In addition, isoellipticine and a related derivative, 7-carbethoxyisoellipticine, were also prepared.
