223913-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223913-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,9,1 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 223913-40:
(8*2)+(7*2)+(6*3)+(5*9)+(4*1)+(3*3)+(2*4)+(1*0)=114
114 % 10 = 4
So 223913-40-4 is a valid CAS Registry Number.

Stereoselective Grignard-type reactions of chiral N,N-dibenzylamino ketones
Reetz, Manfred T.,Schmitz, Alfred
, p. 2737 - 2740 (2007/10/03)
N,N-Dibenzylamino ketones of the type Bn2N(R1)CHC(O)R2, prepared in enantiomerically pure form from α-amino acids, undergo non-chelation controlled Grignard-type reactions with RLi, RMgX or RCeCl2 without any un
