204511-82-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 204511-82-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,1 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204511-82:
(8*2)+(7*0)+(6*4)+(5*5)+(4*1)+(3*1)+(2*8)+(1*2)=90
90 % 10 = 0
So 204511-82-0 is a valid CAS Registry Number.

Enantioselective synthesis of protected isotetronic acids

Enders, Dieter,Dyker, Hubert,Leusink, Frederik R.

, p. 311 - 320 (2007/10/03)

Isotetronic acids are subunits of a number of natural products. They are of interest in agricultural and pharmaceutical research and are important synthetic intermediates. This paper describes the first highly diastereo- and enantioselective synthesis of isotetronic acids in 4 to 5 steps (de, ee > 98%). Key steps in the reaction sequence are the diastereoselective aldol reaction of the 2-oxoesters 5 as their SAEP hydrazones (S)-6 with aldehydes, followed by base-promoted lactonization to the hydrazonolactones 8. Subsequent oxidative cleavage of the hydrazone moiety afforded the enantiomerically pure O-protected isotetronic acids (R)-/(S)-9.
