4281-30-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4281-30-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4281-30:
(6*4)+(5*2)+(4*8)+(3*1)+(2*3)+(1*0)=75
75 % 10 = 5
So 4281-30-5 is a valid CAS Registry Number.

Enantioselective Synthesis of Isoflavanones by Catalytic Dynamic Kinetic Resolution

Qin, Tao,Metz, Peter

supporting information, p. 2981 - 2984 (2017/06/07)

A ruthenium-catalyzed asymmetric transfer hydrogenation of racemic isoflavanones with dynamic kinetic resolution yields virtually enantiopure isoflavanols as single diastereomers. Subsequent oxidation gives rise to isoflavanones in high enantiomeric purit
