Check Digit Verification of cas no
The CAS Registry Mumber 4534-73-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,3 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4534-73:
(6*4)+(5*5)+(4*3)+(3*4)+(2*7)+(1*3)=90
90 % 10 = 0
So 4534-73-0 is a valid CAS Registry Number.

Method for preparing butane tetracarboxylic dianhydride
-
, (2018/10/11)
The invention discloses a method for preparing butane tetracarboxylic dianhydride, and belongs to the field of fine chemical preparation methods. The method comprises the following steps: using maleicanhydride and 1,3-butadiene as starting materials to synthesize tetrahydrophthalic anhydride as an intermediate product through a 1,4-addition reaction in a high temperature molten state; subjectingtetrahydrophthalic anhydride to hydrolysis, ozone oxidation, hydrogen peroxide oxidation reaction to obtain butane tetracarboxylic acid as an intermediate product; using acetic anhydride or propionicanhydride as a dehydrating agent, and subjecting the butane tetracarboxylic acid to synthesize butane tetracarboxylic dianhydride through dehydration closed-ring. Compared with the traditional process, the method has the advantages of mild reaction conditions, high product purity, high yield, and no pollution, and is suitable for large-scale industrial production.
