142796-21-2 Usage

Uses

Used in Pharmaceutical Industry:
Isosilybin A is used as a potential therapeutic agent for the suppression of prostate-specific antigen secretion by androgen-dependent LNCaP cells. This application is particularly relevant in the context of prostate cancer treatment, as it may help in managing the progression of the disease.
Additionally, given its classification as a flavonolignan, Isosilybin A may also have potential applications in other areas of healthcare, such as antioxidant, anti-inflammatory, or hepatoprotective properties. However, further research would be required to confirm these potential uses.

Check Digit Verification of cas no

The CAS Registry Mumber 142796-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,9 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142796-21:
(8*1)+(7*4)+(6*2)+(5*7)+(4*9)+(3*6)+(2*2)+(1*1)=142
142 % 10 = 2
So 142796-21-2 is a valid CAS Registry Number.

Benzodioxans by Oxidative Phenol Coupling. Synthesis of Silybin

Merlini, Lucio,Zanarotti, Antonio,Pelter, Andrew,Rochefort, Malcolm P.,Haensel, Rudolf

, p. 775 - 778 (2007/10/02)

Oxidative coupling of substituted catechols with isoeugenol or coniferyl alcohol in the presence of silver oxide affords 2,3-trans-1,4-benzodioxans in good yield.The reaction is highly regioselective when the catechol bears an alkyl substituent, much less
