10346-44-8 Usage
General Description
(9β)-Cholesta-5,7-dien-3β-ol, also known as 7-Dehydrocholesterol, is a chemical compound that is a precursor to vitamin D3. It is a sterol found in the skin of animals and humans, and plays a crucial role in the synthesis of vitamin D upon exposure to UV radiation. 7-Dehydrocholesterol is also an important component of cell membranes, where it helps maintain their fluidity and stability. Additionally, it has been shown to have antioxidant and anti-inflammatory properties, and may have potential therapeutic applications in treating certain skin conditions and diseases.
Check Digit Verification of cas no
The CAS Registry Mumber 10346-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,4 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 10346-44:
(7*1)+(6*0)+(5*3)+(4*4)+(3*6)+(2*4)+(1*4)=68
68 % 10 = 8
So 10346-44-8 is a valid CAS Registry Number.

Novel Photosensitizers for the E/Z-Isomerization of Trienes. Part 1. Synthesis and Application
Pfoertner, Karl-Heinz
, p. 523 - 526 (2007/10/02)
Uranine and its thioxanthene and selenoxanthene analogues, as well as the disodium salts of o-(6-hydroxy-3-oxo-3H-xanthen-9-yl)benzenesulphonic acid and its thioxanthene and selenoxanthene analogues, show different photosensitizer properties in the E/Z-isomerization of trienes.This has been verified by applying them to the technically useful conversion of tachysterol into previtamin D.The synthesis of the novel photosensitizers with thioxanthene and selenoxanthene moieties are also described.
