936699-55-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 936699-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,6,6,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 936699-55:
(8*9)+(7*3)+(6*6)+(5*6)+(4*9)+(3*9)+(2*5)+(1*5)=237
237 % 10 = 7
So 936699-55-7 is a valid CAS Registry Number.

D-Phg-L-Pro Dipeptide-derived prolinol ligands for highly enantioselective Reformatsky reactions

Shin, Eun-Kyoung,Kim, Hyun Jung,Kim, Yongtai,Kim, Yangmee,Park, Yong Sun

, p. 1933 - 1935 (2006)

Optically pure N-aminoethyl prolinol derivatives 3a-c have been prepared from the dynamic kinetic resolution of N-(α-bromo-α-phenylacetyl) proline ester 1 in asymmetric nucleophilic substitution and subsequent reduction. The peptide-derived prolinols are

Asymmetric dehydration of β-hydroxy esters and application to the syntheses of flavane derivatives

Choi, Eui Ta,Lee, Min Hee,Kim, Yongtae,Park, Yong Sun

, p. 1515 - 1522 (2008/09/18)

Catalytic asymmetric dehydration of β-aryl or alkyl substituted β-hydroxy esters via kinetic resolution has been investigated. A brief survey of 10 different chiral ligands is conducted to examine the effects of chiral ligand structure on selectivity of t

Enantioselective reformatsky reaction induced by chiral β-amino alcohols

Andres, Jose M.,Martin, Yolanda,Pedrosa, Rafael,Perez-Encabo, Alfonso

, p. 3787 - 3794 (2007/10/03)

Reformatsky reagent derived from tert-butyl α-bromoacetate adds to carbonyl compounds in the presence of chiral amino alcohols leading to β-hydroxy tert-butyl eaters with good e.e. The enantioface differentiation depends on the reaction conditions and on
