188909-23-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188909-23-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,0 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188909-23:
(8*1)+(7*8)+(6*8)+(5*9)+(4*0)+(3*9)+(2*2)+(1*3)=191
191 % 10 = 1
So 188909-23-1 is a valid CAS Registry Number.

Diastereoselectivity of the reactions of organolithium reagents with protected erythrulose oximes

Marco,Carda,Murga,Rodriguez,Falomir,Oliva

, p. 1679 - 1701 (2007/10/03)

The addition of organolithium reagents to the C=N bond of several erythrulose-derived chiral (E)- and (Z)-ketoxime ethers has been shown to be highly diastereoselective in the case of the (E)-isomers. Chelated and nonchelated transition states have been proposed to rationalize these results, with additional support of computational methods.

Diastereoselective additions of organolithium reagents to the C=N bond of protected erythrulose oxime ethers. Synthesis of enantiopure α,α-disubstituted α-aminoacids

Marco, J. Alberto,Carda, Miguel,Murga, Juan,Gonzalez, Florenci,Falomir, Eva

, p. 1841 - 1844 (2007/10/03)

The addition of organolithium reagents to the C=N bond of several erythrulose-derived chiral (E)- and (Z)-ketoxime ethers has been shown to be highly diastereoselective for the (E)-isomers. A chelated transition state has been proposed to explain this result. The addition products were converted into the two α,α-disubstituted α-aminoacids (R)-2-(-)-methylserine and (R)-(+)-2-phenylserine.
