63882-05-3

9,10-Secocholesta-5(10),7-dien-3-ol, (3b,7E)-, also known as 7-dehydrocholesterol, is a naturally occurring steroid compound found in the skin. It is a key intermediate in the biosynthesis of vitamin D3, playing a crucial role in the conversion process when exposed to ultraviolet B (UVB) radiation from sunlight. 9,10-Secocholesta-5(10),7-dien-3-ol,(3b,7E)- (9CI) is derived from cholesterol and has a unique structure characterized by a double bond at the 7th position and a hydroxyl group at the 3rd position. It is an important precursor in the metabolic pathway leading to the production of vitamin D3, which is essential for maintaining healthy bones and immune system function. The chemical's systematic name, 9,10-Secocholesta-5(10),7-dien-3-ol, (3b,7E)-, reflects its specific structural features, with the "secocholesta" indicating a broken ring structure, "dien" signifying the presence of two double bonds, and the numerical subscripts and prefixes detailing the positions and configurations of these bonds and the hydroxyl group.

63882-05-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63882-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,8 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 63882-05:
(7*6)+(6*3)+(5*8)+(4*8)+(3*2)+(2*0)+(1*5)=143
143 % 10 = 3
So 63882-05-3 is a valid CAS Registry Number.

Features of previtamin D cis-trans isomerization in the nematic LC matrices: Orientation and cholesteric order effects

Gvozdovskyy,Orlova,Terenetskaya

, p. 325/[653]-332/[660] (2005)

For the first time 7-dehydrocholesterol (7-DHC, provitamin D3) photoisomerization was studied in nematic LC matrices (ZLI-1695, ZhK-805) in comparison with ethanol solution using UV absorption spectroscopy. Dissolution of chiral 7-DHC molecules in the nematic LCs induces cholesteric phase, and dramatic effect of the cholesteric pitch value on the spectral kinetics has been revealed. Significant increase in trans-isomer accumulation was observed as the cholesteric pitch was reduced from 2200 to 25 mkm. Noticeable effect of the LC orientation has been observed as well.
