20520-67-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20520-67-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,2 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20520-67:
(7*2)+(6*0)+(5*5)+(4*2)+(3*0)+(2*6)+(1*7)=66
66 % 10 = 6
So 20520-67-6 is a valid CAS Registry Number.

Regioselective lithiation of benzyl imidazole: Synthesis and evaluation of new organocatalysts for trans-diol functionalization.

El-Mansy, Mohamed,Ghosh, Ankan,Cheong, Paul Ha-Yeon,Carter, Rich

supporting information, p. 3131 - 3139 (2019/09/03)

Benzyl imidazole was successfully lithiated using n-BuLi at ?78 °C and verified by deuterium incorporation. The chemical reaction of the lithiated benzimidazole was explored with a series of different electrophiles. This approach was utilized to synthesiz

3-Deazaneplanocin A and neplanocin a analogues and their effects on apoptotic cell death

Tam, Eric K.W.,Nguyen, Tuan Minh,Lim, Cheryl Z.H.,Lee, Puay Leng,Li, Zhimei,Jiang, Xia,Santhanakrishnan, Sridhar,Tan, Tiong Wei,Goh, Yi Ling,Wong, Sze Yue,Yang, Haiyan,Ong, Esther H.Q.,Hill, Jeffrey,Yu, Qiang,Chai, Christina L.L.

supporting information, p. 173 - 182 (2015/04/14)

3-Deazaneplanocin A (DzNep) is a potential epigenetic drug for the treatment of various cancers. DzNep has been reported to deplete histone methylations, including oncogenic EZH2 complex, giving rise to epigenetic modifications that reactivate many silenced tumor suppressors in cancer cells. Despite its promise as an anticancer drug, little is known about the structure-activity relationships of DzNep in the context of epigenetic modifications and apoptosis induction. In this study, a number of analogues of DzNep were examined for DzNeplike ability to induce synergistic apoptosis in cancer cells in combination with trichostatin A, a known histone deacetylase (HDAC) inhibitor. The structure-activity relationship data thus obtained provide valuable information on the structural requirements for biological activity. The studies identified three compounds that show similar activities to DzNep. Two of these compounds show good pharmacokinetics and safety profiles. Attempts to correlate the observed synergistic apoptotic activities with measured S-adenosylhomocysteine hydrolase (SAHH) inhibitory activities suggest that the apoptotic activity of DzNep might not be directly due to its inhibition of SAHH.

Metal-free, organocatalytic syn diacetoxylation of alkenes

Zhong, Wenhe,Liu, Shan,Yang, Jun,Meng, Xiangbao,Li, Zhongjun

supporting information; experimental part, p. 3336 - 3339 (2012/08/29)

A novel method for the organocatalytic syn diacetoxylation of alkenes has been developed using aryl iodides as efficient catalysts. A broad range of substrates, including electron-rich as well as electron-deficient alkenes, are smoothly transformed by the new procedure, furnishing the desired products in good to excellent yields with high diastereoselectivity (up to >19:1 dr).
