131063-58-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131063-58-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,6 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131063-58:
(8*1)+(7*3)+(6*1)+(5*0)+(4*6)+(3*3)+(2*5)+(1*8)=86
86 % 10 = 6
So 131063-58-6 is a valid CAS Registry Number.

Synthesis of optically active 2,5-dialkylcyclohexane-1,4-diols and their application in the asymmetric oxidation of sulfides

Sun, Jiangtao,Yang, Minghua,Dai, Zhenya,Zhu, Chengjian,Hu, Hongwen

, p. 2513 - 2518 (2008)

A simple and efficient approach to obtain optically pure 1,4-diols was established. The asymmetric oxidation of sulfides to sulfoxides with cumyl hydroperoxide in moderate yields and moderate to high enantioselectivities (up to 84%) catalyzed by chiral Ti/ 1,4-diols complexes has been achieved. A 76% ee value was obtained in the asymmetric synthesis of esomeprazole. Georg Thieme Verlag Stuttgart.

Syntheses of novel chiral 2,5-dialkyl-7-azabicyclo[2.2.1]heptanes and 2,5-dialkyl-7-thiobicyclo[2.2.1]heptanes

Xiao, Dengming,Zhang, Zhaoguo,Jiang, Qiongzhong,Zhang, Xumu

, p. 5331 - 5334 (2007/10/03)

New C2-symmetric chiral amines with a rigid bicyclic framework have been synthesized via hydrogenation of monoazides catalyzed by 5% Pd/C in methanol. Enantiomerically pure 2,5-dialkyl-7-thiobicyclo[2.2.1]heptanes were made from readily available materials.
