124843-18-1 Usage
General Description
Pectin is a soluble dietary fiber extracted from apple pomace, which is a byproduct of apple juice production. It is composed of a complex polysaccharide structure made up of galacturonic acid and its methyl ester. Pectin is commonly used as a gelling agent in food products such as jams and jellies, as well as a thickening agent in fruit fillings and dairy products. It is known for its ability to form a gel when mixed with sugar and acid, and it also has potential health benefits such as promoting digestive health and lowering cholesterol levels.
Check Digit Verification of cas no
The CAS Registry Mumber 124843-18-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,8,4 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124843-18:
(8*1)+(7*2)+(6*4)+(5*8)+(4*4)+(3*3)+(2*1)+(1*8)=121
121 % 10 = 1
So 124843-18-1 is a valid CAS Registry Number.

Identification and characterization of pectenotoxin (PTX) 4 and PTX7 as spiroketal stereoisomers of two previously reported pectenotoxins

, p. 2475 - 2480 (2007/10/03)
Pectenotoxins (PTXs) isolated from the scallon Patinopecten yessoensis were shown to be involved in an episode of diarrhetic shellfish poisoning (DSP). A total of eight analogues (PTX1-PTX7 and PTX10) have been isolated to date, and the structures of four of these analogues (PTX1, PTX2, PTX3, and PTX6) have already been elucidated. Here, we report the characterization of PTX4 and PTX7 as 7-epi-PTX1 and 7-epi-PTX6, respectively, on the basis of NMR data and an acid-catalyzed chemical interconversion. The structures of two new artifacts, PTX8 and PTX9, produced following this treatment are also reported.
