267653-10-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 267653-10-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,7,6,5 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 267653-10:
(8*2)+(7*6)+(6*7)+(5*6)+(4*5)+(3*3)+(2*1)+(1*0)=161
161 % 10 = 1
So 267653-10-1 is a valid CAS Registry Number.

Synthesis of cyclopeptide alkaloids by cyclooligomerization of dipeptidyl oxazolines

Wipf, Peter,Miller, Chris P,Grant, Charsetta M

, p. 9143 - 9150 (2000)

Cyclodehydration of Cbz-valylthreonine methyl esters with Burgess reagent provides access to cis- and trans-oxazoline segments for cyclooligomerization reactions. The ratio of 12-, 18-, 24-, and larger-ring macrocycles obtained in this process is kinetica

Synthesis of functionalized oxazolines and oxazoles with DAST and Deoxo-Fluor.

Phillips,Uto,Wipf,Reno,Williams

, p. 1165 - 1168 (2007/10/03)

[formula: see text] A mild and highly efficient cyclization of beta-hydroxy amides to oxazolines is described using DAST and Deoxo-Fluor reagents. A one-pot protocol for the synthesis of oxazoles from beta-hydroxy amides is also presented.
