2931-89-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2931-89-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,3 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2931-89:
(6*2)+(5*9)+(4*3)+(3*1)+(2*8)+(1*9)=97
97 % 10 = 7
So 2931-89-7 is a valid CAS Registry Number.

Containing 8-ethoxy-3-nitro -2H-benzopyran structure of the hydrazone derivatives and the preparation method and application

-

Paragraph 0037-0040, (2017/01/05)

The invention belongs to the technical field of chemistry, and relates to acylhydrazone derivatives with an 8-ethoxy-3-nitro-2H-benzopyran structure as well as a preparation method and application thereof. The structural general formula (I) of the derivatives is as shown in the specification, wherein R1 is independent aryl or substituted aryl with 6-10 carbon atoms, or heteroaryl or substituted heteroaryl with 5-10 atoms; R2 is independent H, methyl or ethyl. Ethyl vanillin is used as a raw material, the acylhydrazone derivatives with the 8-ethoxy-3-nitro-2H-benzopyran structure are synthesized through acylation, cyclization and condensation, and anti-tumor activity experiment researches are performed. Experimental results show that the compounds disclosed by the invention have good tumor cell proliferation activity resistance.

Process for the preparation of 3-carboxy-4-hydroxybenzaldehides and derivatives thereof

-

, (2008/06/13)

The present invention concerns a process for the preparation of 3-carboxy-4-hydroxybenzaldehydes and derivatives thereof from phenolic compounds carrying formyl and/or hydroxymethyl groups in the 2 and 4 positions. The invention also concerns the preparation of 4-hydroxybenzaldehydes from 3-carboxy-4-hydroxybenzaldehydes. More particularly, the invention concerns the preparation of 3-methoxy-4-hydroxybenzaldehyde and 3-ethoxy-4-hydroxybenzaldehyde, respectively known as "vanillin" and "ethylvanillin". The process for the preparation of 3-carboxy-4-hydroxybenzaldehyde is characterized in that the group in the 2 position in a phenolic compound carrying formyl and/or hydroxymethyl groups in the 2 and 4 positions is selectively oxidized to a carboxy group, and optionally a hydroxymethyl group in the 4 position is selectively oxidized to a formyl group. A successive decarboxylation step for a 3-carboxy-4-hydroxybenzaldehyde produces a 4-hydroxybenzaldehyde.
