53093-47-3 Usage
General Description
Proto-Pb is a chemical compound consisting of lead atoms that have been artificially created under high-energy collisions in particle accelerators. It is considered a short-lived, highly unstable isotope of lead with atomic number 208. The creation of Proto-Pb is significant in nuclear physics as it provides insights into the behavior and properties of superheavy elements. Its existence and characteristics also contribute to the ongoing research and understanding of the stability and structure of atomic nuclei at the edge of stability. Additionally, Proto-Pb has potential applications in advanced nuclear technologies and the study of fundamental forces and particles in the universe.
Check Digit Verification of cas no
The CAS Registry Mumber 53093-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,0,9 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53093-47:
(7*5)+(6*3)+(5*0)+(4*9)+(3*3)+(2*4)+(1*7)=113
113 % 10 = 3
So 53093-47-3 is a valid CAS Registry Number.

The constituents of the leaves, stems and underground parts of Trachycarpus fortunei (HOOK.) H.Wendl. (Palmae) have been investigated.Glucoluteolin (3), luteolin 7-O-rutinoside (=scolymoside, 4) and methyl proto-Pb (6) from the leaves, dioscin (1), Pb (2), methyl protodioscin (5) and methyl proto-Pb (6) from the stems, and dioscin (1) and methyl proto-Pb (6) from the underground parts were isolated and identified.This is the first report of the isolation of steroidal saponins from Palmae plants and these results are interesting from the standpoint of chemotaxonomy. keywords - Trachycarpus fortunei; Palmae; steroidal saponin; furostanol oligoside; diosgenin; proto-diosgenin; flavone glycoside; luteolin; glucoluteolin; scolymoside
