914220-85-2 Usage
General Description
N-methoxy-N-methyl-2-oxopropanamide, also known as MMPA, is a chemical compound with the molecular formula C5H11NO3. It is a white solid at room temperature and is commonly used as a reagent in organic synthesis. MMPA is primarily used as a protecting group for amines in peptide synthesis, as well as a mild base in organic reactions. It is also used as a solvent in some chemical processes. MMPA is considered to have low toxicity, but proper safety precautions should still be taken when handling it in the laboratory.
Check Digit Verification of cas no
The CAS Registry Mumber 914220-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,4,2,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 914220-85:
(8*9)+(7*1)+(6*4)+(5*2)+(4*2)+(3*0)+(2*8)+(1*5)=142
142 % 10 = 2
So 914220-85-2 is a valid CAS Registry Number.

Asymmetric hydrogenation of α-keto Weinreb amides has been realized with [Ru((S)-Sunphos)(benzene)Cl]Cl as the catalyst and CeCl3· 7H2O as the additive. A series of enantiopure α-hydroxy Weinreb amides (up to 97% ee) have been obtained. Catalytic amount of CeCl 3·7H2O is essential for the high reactivity and enantioselectivity and the ratio of CeCl3·7H2O to [Ru((S)-Sunphos)(benzene)Cl]Cl plays an important role in the hydrogenation reaction.
