944335-23-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 944335-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,3,3 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 944335-23:
(8*9)+(7*4)+(6*4)+(5*3)+(4*3)+(3*5)+(2*2)+(1*3)=173
173 % 10 = 3
So 944335-23-3 is a valid CAS Registry Number.

An efficient approach to the stereoselective synthesis of 2,6-disubstituted dihydropyrans via stannyl-Prins cyclization

Dziedzic, Magdalena,Furman, Bart?omiej

, p. 678 - 681 (2008/09/16)

A general method has been developed for the stereoselective construction of 2,6-disubstituted dihydropyrans based on the Lewis acid-catalyzed intramolecular reactions of oxocarbenium ions with vinylstannanes. This novel methodology was applied to the enan
