Check Digit Verification of cas no

The CAS Registry Mumber 17669-29-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,6 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17669-29:
(7*1)+(6*7)+(5*6)+(4*6)+(3*9)+(2*2)+(1*9)=143
143 % 10 = 3
So 17669-29-3 is a valid CAS Registry Number.

Lanthanide triflate-catalyzed 1,3-dipolar cycloaddition reactions of polymer-supported nitrones with alkenes for the preparation of diverse 2- isoxazoline derivatives

Kobayashi, Shu,Akiyama, Ryo

, p. 9211 - 9214 (1998)

1,3-Dipolar cycloaddition reactions of polymer-supported nitrones with alkenes proceeded smoothly in the presence of a catalytic amount of a lanthanide triflate to afford the corresponding 2-isoxazolines in high yields. Diverse 2-isoxazoline derivatives were prepared based on these solid- phase reactions.
