Check Digit Verification of cas no
The CAS Registry Mumber 77-08-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77-08:
(4*7)+(3*7)+(2*0)+(1*8)=57
57 % 10 = 7
So 77-08-7 is a valid CAS Registry Number.

Paragraph 0099; 0100; 0101; 0102, (2020/07/24)
The invention provides a tetramine monomer containing a spiro structure and a preparation method and application thereof, and polyamide and preparation and application thereof, and belongs to the technical field of gas membrane separation. According to the invention, a spiro center in a microporous polymer (PIMs) is introduced into a tetramine monomer, so that the tetramine monomer containing an aliphatic group (methylene) and having a microporous structure can be obtained. The polyamide film prepared from the tetramine monomer has the characteristics of high gas selectivity, high permeability, good solubility, good selectivity and the like, also has excellent thermal properties, and can be used as a novel polyamide gas separation film.

We present our preliminary work on the fabrication of polyimide hollow sphere by reprecipitation. Through fine-tuning the PAA concentration, many intriguing shapes, including deflated capsules, bowl-shaped and dimple-like hollow spheres can be obtained. Adding salt to the PAA solution helps the formation of PI hollow spheres with complete shells. The morphologies can be fixed through imidization, thus obtaining a controllable and reproducible method to prepare high-performance polyimide hollow spheres with various morphologies.
