23393-20-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23393-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,9 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23393-20:
(7*2)+(6*3)+(5*3)+(4*9)+(3*3)+(2*2)+(1*0)=96
96 % 10 = 6
So 23393-20-6 is a valid CAS Registry Number.

First Total Synthesis of Mycothiol and Mycothiol Disulfide

Lee, Sungwon,Rosazza, John P. N.

, p. 365 - 368 (2007/10/03)

(Matrix presented) The first total synthesis of mycothiol and mycothiol disulfide was achieved by linking D-2,3,4,5,6-penta-O-acetyl-myo-inositol, O-(3,4,6-tri-O-acetyl)-2-azido-2-deoxy-α,β-D-glucopyranosyl) trichloroacetimidate, and N,S-diacetyl-L-cysteine and deprotecting peracetylated mycothiol. The first full spectral characterization is reported for underivatized mycothiol. The structure of mycothiol was confirmed by spectral analysis of the known bimane derivative.

Synthesis of racemic 3-methylphosphonate analogues of myo-inositol 3,4-bis- and 1,3,4-trisphosphate

Dreef,Tuinman,Lefeber,Elie,Van Der Marel,Van Boom

, p. 4709 - 4722 (2007/10/02)

The partially benzyl protected myo-inositol derivatives 11a and 11b, the C-4 and C-1,4 hydroxyl function(s) of which are protected with temporary trans-prop-1-enyl protecting group(s), were readily converted into the respective title compounds 18a and 18b by sequential methylphosphonylation, mild cleavage of the trans-prop-1-enyl group(s), phosphorylation and removal of all permanent benzyl protecting groups.
