97359-38-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97359-38-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,3,5 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 97359-38:
(7*9)+(6*7)+(5*3)+(4*5)+(3*9)+(2*3)+(1*8)=181
181 % 10 = 1
So 97359-38-1 is a valid CAS Registry Number.

Cationic ring-opening polymerization of 1,3-benzoxazines: Mechanistic study using model compounds

Chutayothin, Papinporn,Ishida, Hatsuo

experimental part, p. 4562 - 4572 (2011/10/18)

The benzoxazine monomer is used to simplify the study of the benzoxazine initiation mechanism. The HPLC retention time and the 1H NMR spectra of crude products from the benzoxazine reaction are compared with the results from a vast number of pure model compounds, which are synthesized based on the hypothesized mechanisms. Products involved in the process are identified, with species having benzoxazine structures, Mannich base and other components (acetal, nonacetal phenoxy structures, and methylene bridge structure). Initiation mechanisms of benzoxazine, e.g., the oxygen protonation and the nitrogen protonation, are proposed.
