128233-32-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128233-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,3 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128233-32:
(8*1)+(7*2)+(6*8)+(5*2)+(4*3)+(3*3)+(2*3)+(1*2)=109
109 % 10 = 9
So 128233-32-9 is a valid CAS Registry Number.

Isolation and Structure Elucidation of Ergokonin A and B; Two New Antifungal Sterol Antibiotics from Trichoderma koningii

Augustiniak, Hermann,Forche, Edgar,Reichenbach, Hans,Wray, Viktor,Graefe, Udo,Hoefle, Gerhard

, p. 361 - 366 (2007/10/02)

Isolation and structure elucidation by 2D-NMR spectroscopy of the two new antifungal sterol antibiotics ergokonin A (1) and B (2a) from Trichoderma koningii are described.The structures of 1 and 2a are derived from ergosterol and characterized by an 18-carboxy group.In addition ergokonin A (1) is esterified at the 3-hydroxy group with (2S,3S)-3-hydroxyleucine 3-O-sulfate (3c).In the course of structure elucidation of the amino acid residue the stereoisomers of 3-hydroxyleucine N-sulfamate and 3-O-sulfate (3b, c) have been synthesized and characterized by NMR spectroscopy.
