216393-12-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 216393-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,3,9 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 216393-12:
(8*2)+(7*1)+(6*6)+(5*3)+(4*9)+(3*3)+(2*1)+(1*2)=123
123 % 10 = 3
So 216393-12-3 is a valid CAS Registry Number.

Alcohol cross-coupling for the kinetic resolution of diols via oxidative esterification

Hofmann, Christine,Schümann, Jan M.,Schreiner, Peter R.

, p. 1972 - 1978 (2015/02/19)

We present an organocatalytic C-O-bond cross-coupling strategy to kinetically resolve racemic diols with aromatic and aliphatic alcohols, yielding enantioenriched esters. This one-pot protocol utilizes an oligopeptide multicatalyst, m-CPBA as the oxidant, and N,N-diisopropylcarbodiimide as the activating agent. Racemic acyclic diols as well as trans-cycloalkane-1,2-diols were kinetically resolved, achieving high selectivities and good yields for the products and recovered diols.

Kinetic resolution of trans-cycloalkane-1,2-diols via Steglich esterification

Hrdina, Radim,Mueller, Christian E.,Schreiner, Peter R.

supporting information; experimental part, p. 2689 - 2690 (2010/07/08)

We describe the efficient and highly enantioselective kinetic resolution of trans-cycloalkane-1,2-diols utilizing an enantioselective Steglich reaction with a variety of carboxylic acids that form the corresponding anhydrides in situ.
