682770-63-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 682770-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,2,7,7 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 682770-63:
(8*6)+(7*8)+(6*2)+(5*7)+(4*7)+(3*0)+(2*6)+(1*3)=194
194 % 10 = 4
So 682770-63-4 is a valid CAS Registry Number.

Candida Rugosa lipase-catalyzed kinetic resolution of β-hydroxy- β-arylpropionates and δ-hydroxy-δ-aryl-β-oxo-pentanoates

Xu, Chengfu,Yuan, Chengye

, p. 2169 - 2186 (2007/10/03)

A simple and convenient method was reported for the preparation of optically active β-hydroxy-β-arylpropionates, δ-hydroxy-δ- aryl-β-oxo-pentanoates and their butyryl derivatives via CRL-catalyzed hydrolysis. The optically active products are potential precursors of some chiral pharmaceuticals and natural products.

A Chemoenzymatic Approach to Optically Active 5-Hydroxy-3-oxocarboxylates

Xu, Chengfu,Zhang, Yonghui,Yuan, Chengye

, p. 485 - 488 (2007/10/03)

Enzymatic hydrolysis was applied to the preparation of certain chiral 5-hydroxy-3-oxo-carboxylates that are potential precursors for natural product synthesis via the formation of lactone derivatives and tetrahydropyran rings.
