Check Digit Verification of cas no

The CAS Registry Mumber 37853-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,8,5 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 37853-11:
(7*3)+(6*7)+(5*8)+(4*5)+(3*3)+(2*1)+(1*1)=135
135 % 10 = 5
So 37853-11-5 is a valid CAS Registry Number.

STUDIES ON DIHYDROPYRIDINE DERIVATIVES-I 4,7-DIHYDROISOXAZOLOPYRIDINES

Yamamori, Teruo,Hiramatu, Yoshiharu,Sakai, Katunori,Adachi, Ikuo

, p. 913 - 918 (2007/10/02)

Reactions of 5-aminoisoxazoles with α,β-unsaturated ketones in t-butanol on heating afforded 4,7-dihydroisoxazolopyridines.However, when the reactions were carried out at 20 deg C using ethylene glycol as the solvent, the kinetically controlled amino adducts were obtained in excellent yields.The amino adducts were converted into the thermodynamically controlled 4,7-dihydroisoxazolopyridines by heating.Tentative mechanisms for the reaction are also presented.
