66879-51-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66879-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,7 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66879-51:
(7*6)+(6*6)+(5*8)+(4*7)+(3*9)+(2*5)+(1*1)=184
184 % 10 = 4
So 66879-51-4 is a valid CAS Registry Number.

Total Synthesis of (-)-Bacchopetiolone via an Asymmetric Hydroxylative Phenol Dearomatization/[4+2]-Dimerization Cascade Promoted by a Novel Salen-Type Chiral Iodane

Coffinier, Romain,Assal, Mourad El,Peixoto, Philippe A.,Bosset, Cyril,Miqueu, Karinne,Sotiropoulos, Jean-Marc,Pouységu, Laurent,Quideau, Stéphane

, p. 1120 - 1123 (2016/03/15)

The first total and biomimetic synthesis of the natural bis(sesquiterpene) (-)-bacchopetiolone (revised structure) was completed through a highly diastereoselective hydroxylative phenol dearomatization/[4+2]-dimerization cascade conversion of (+)-curcuphe

Synthesis of bisabolane sesquiterpenes: A Johnson-Claisen rearrangement approach

Du, Zhen Ting,Yu, Hong Rui,Xu, Yan,Li, Yong,Li, An Pai

, p. 813 - 815 (2011/11/12)

Several bisabolane sesquiterpenes, (±)-curcumene, (±)-curcuphenol, (±)-curcudiol and (±)-curcuhydroquinone, have been synthesized in racemic form and fully characterized. The salient characteristic of our approach is that a Johnson-Claisen arrangement was

Facile syntheses of (±)-curcuphenol-(±)-curcudiol-±)- curcuhydroquinone, and (±)-curcuquinone

Du, Zhenting,Li, Yong,Wang, Yin,Ding, Lichun,Gao, Jinming

experimental part, p. 1920 - 1926 (2010/09/09)

The syntheses of (±)-curcuphenol 1, (±)-curcudiol 2, (±)-curcuhydroquinone 3, and (±)-curcuquinone 4 have been achieved. The key steps involved in the syntheses were the Reformatsky reaction and hydrogenation reaction. Copyright
