101711-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 101711-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,7,1 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 101711-90:
(8*1)+(7*0)+(6*1)+(5*7)+(4*1)+(3*1)+(2*9)+(1*0)=74
74 % 10 = 4
So 101711-90-4 is a valid CAS Registry Number.

Syntheses of all the stereoisomers of butanol type 1,7-seco-2,7′-cyclolignane

Yamauchi, Satoshi,Tomiyama, Chisato,Wukirsari, Tuti,Nishiwaki, Hisashi

, p. 19 - 28 (2014)

All the stereoisomers of butanol type 1,7-seco-2,7′-cyclolignane were stereoselectively synthesized by employing (S)- and (R)-Evans' auxiliaries to construct the stereochemistry. (+)- and (-)-Kadangustin J and their diastereomers were also prepared. The optical purity of the synthesized butanol type 1,7-seco-2,7′-cyclolignane was more than 99%ee.

Asymmetric synthesis of (E)-dehydroapratoxin A

Ma, Jing-Yi,Huang, Wei,Wei, Bang-Guo

scheme or table, p. 4598 - 4601 (2011/09/30)

An asymmetric approach to key intermediate 17 starting from lactone 7 is described, in which Evan's alkylation and CBS-catalyzed reduction are used for construction of the chiral centers, respectively. Thus, the synthesis of (E)-dehydroapratoxin A 6 could
