Check Digit Verification of cas no

The CAS Registry Mumber 203191-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,1,9 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203191-70:
(8*2)+(7*0)+(6*3)+(5*1)+(4*9)+(3*1)+(2*7)+(1*0)=92
92 % 10 = 2
So 203191-70-2 is a valid CAS Registry Number.

7-CARBOXYMETHYLOXY-3', 4', 5-TRIMETHOXY FLAVONE MONOHYDRATE, THE PREPARATION METHOD AND USES THEREOF

-

Page/Page column 27-28, (2008/06/13)

The present invention relates to 7-carboxymethyloxy-3’, 4’, 5-trimethoxy flavone.monohydrate which is a non hygroscopic product suitable for the preparation of metered dose of 7-carboxymethyloxy-3’, 4’, 5-trimethoxy flavone having protective activity for gastrointestinal tract including the colon, and a preparation method and uses thereof. 7-carboxymethyloxy-3’, 4’, 5-trimethoxy flavone.monohydrate of the present invention has advantages such as mucus protecting activity for gastrointestinal tract including the colon, convenience for handling and storage under ordinary humidity owing to its non-hygroscopicity, and ability to contain an active compound consistently for the formulation production of a medicine. In addition, the preparation method of 7-carboxymethyloxy-3’, 4’, 5-trimethoxy flavone.monohydrate of the present invention reduces long steps of total synthesis and requires mild conditions for the production of a compound because autoclave condition is not necessary for methylation in this case, and makes mass-production possible without any purification process such as recrystallization or column chromatography.
