Check Digit Verification of cas no

The CAS Registry Mumber 3573-76-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,7 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3573-76:
(6*3)+(5*5)+(4*7)+(3*3)+(2*7)+(1*6)=100
100 % 10 = 0
So 3573-76-0 is a valid CAS Registry Number.

Preparation method of bicyclo-tetracarboxylic dianhydride

-

Paragraph 0010; 0020-0029; 0030-0039; 0040-0049, (2018/06/04)

The invention discloses a preparation method of bicyclo-tetracarboxylic dianhydride, and belongs to the field of a preparation method of fine chemicals. In the technical scheme, the preparation methodis mainly characterized in that with cheap phthalic acid being initial raw materials, 3,5-cyclopentadiene-1,2-dicarboxylic acid is generated through electrolytic reduction; then the 3,5- cyclopentadiene-1,2-dicarboxylic acid reacts with maleic anhydride, acetic anhydride or propionic anhydride is used as solvent and a dehydrating agent, and bicyclo-tetracarboxylic dianhydride is generated under 1,4-addition reaction and dehydrating ring-closure reaction. In the scheme, the preparation method has the advantages of being low in manufacturing cost, high in utilization rate of atoms, high in yield, mild in reaction condition, environmentally friendly and the like.

Method for preparing bicyclic structure tetracarboxylic dianhydride

-

Paragraph 0032; 0036; 0045; 0058, (2018/11/26)

The invention discloses a method for preparing bicyclic structure tetracarboxylic dianhydride and belongs to the field of fine chemical preparation methods. The main technical scheme is that phthalicacid serves as a starting raw material, bicyclic tetracarboxylic dianhydride with a full-exterior structure is synthesized by reaction of five steps including electrolytic reduction, 1,4-addition, methyl esterification, hydrogenation reduction, transesterification and dehydration ring closure. According to the scheme, compared with a traditional preparation process, the method has the advantages of fewer operation steps, mild reaction conditions and high yield, and the method is suitable for large-scale industrial production.

Diels-Alder Reactions with 2H-Pyran-2-ones: Reactivity and Selectivity

Effenberger, Franz,Ziegler, Thomas

, p. 1339 - 1346 (2007/10/02)

2H-Pyran-2-ones 1 react with maleic anhydride (2) in a double Diels-Alder reaction to give bicyclooct-2-ene-5,6:7,8-tetracarboxylic dianhydrides 5; the syn/syn structure was established.As expected, the reactivity of 1 was increased by electron donor substituents (OR, alkyl) and diminished by electron withdrawing substituents (CO2R).The steric influence of substituents at C-6 also decrease the reactivity of 1. - Methyl propiolate (6) and phenylacetylene (9) react with 1 to form the Diels-Alder products 7 which suffer CO2 elimination to yield methyl benzoates 8 with low and biphenyls 10 with high regioselectivity, respectively.
