188726-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188726-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,2 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 188726-77:
(8*1)+(7*8)+(6*8)+(5*7)+(4*2)+(3*6)+(2*7)+(1*7)=194
194 % 10 = 4
So 188726-77-4 is a valid CAS Registry Number.

A General Synthetic Procedure for N-Unsubstituted Isoxazolidines via Nitrone-Olefin Cycloaddition. Remarkable Catalytic Effect of Bu2SnO
Abiko, Atsushi
, p. 357 - 358 (2007/10/02)
The remarkable catalysis of Bu2SnO for nitrone formation in the nitrone-olefin cycloaddition reaction has been discovered, and has led to the development of a general method for the synthesis of N-unsubstituted isoxazolidine derivatives.
