3647-33-4 Usage
General Description
Ethyl 2,3-anhydro-4,5-dideoxy-3-C-methylpentonate is a chemical compound with a complex molecular structure. It is a derivative of 3-C-methylpentonate, which is a five-carbon sugar derivative. The compound contains an ethyl group, indicating the presence of an ethyl functional group attached to the molecule. The 2,3-anhydro and 4,5-dideoxy substitutions suggest that certain oxygen atoms within the molecule have been replaced or modified. ethyl 2,3-anhydro-4,5-dideoxy-3-C-methylpentonate likely has specific applications in organic chemistry, pharmaceuticals, or other industries where the manipulation and study of complex molecules is important.
Check Digit Verification of cas no
The CAS Registry Mumber 3647-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,4 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3647-33:
(6*3)+(5*6)+(4*4)+(3*7)+(2*3)+(1*3)=94
94 % 10 = 4
So 3647-33-4 is a valid CAS Registry Number.

Continuing studies on the cyanobacterium Lyngbya sp.: Isolation and structure determination of 15-norlyngbyapeptin A and lyngbyabellin D
Williams, Philip G.,Luesch, Hendrik,Yoshida, Wesley Y.,Moore, Richard E.,Paul, Valerie J.
, p. 595 - 598 (2003)
Re-collections of the cyanobacterium Lyngbya sp. have yielded two more members of the lyngbyapeptin and lyngbyabellin families. The gross structures of 15-norlyngbyapeptin A (1) and lyngbyabellin D (3) were deduced through standard 2D NMR techniques, with the absolute configuration of both elucidated through degradation and comparison with commercially available and synthetic standards. Degradation to the α-amino acid and NOE correlations determined the absolute and relative configuration of the 4-amino-3-hydroxy-5-methylhexanoic acid unit in 3. Lyngbyabellin D (3) displayed an IC50 value of 0.1 μM against the KB cell line.
