Check Digit Verification of cas no
The CAS Registry Mumber 74319-96-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,1 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74319-96:
(7*7)+(6*4)+(5*3)+(4*1)+(3*9)+(2*9)+(1*6)=143
143 % 10 = 3
So 74319-96-3 is a valid CAS Registry Number.

An improved synthesis of 5,6-dimethylxanthenone-4-acetic acid (DMXAA)
Atwell, Graham J,Yang, Shangjin,Denny, William A
, p. 825 - 828 (2007/10/03)
5,6-Dimethylxanthenone-4-acetic acid (DMXAA) is a novel anticancer agent with a number of unique activities, and is in clinical trial. The current synthesis of DMXAA involves six steps, beginning with a heterogeneous reaction to form an isonitrosoacetanilide, and gives an overall yield of 11% from 2,3-dimethylaniline. We report an alternative synthesis of the key intermediate 3,4-dimethylanthranilic acid via nitration of 3,4-dimethylbenzoic acid and separation of the key desired isomer by ready crystallisation. This, together with improvements in the rest of the synthesis, provide a shorter and higher-yielding route to DMXAA (22% overall from 3,4-dimethylbenzoic acid).
