100349-05-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100349-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,3,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 100349-05:
(8*1)+(7*0)+(6*0)+(5*3)+(4*4)+(3*9)+(2*0)+(1*5)=71
71 % 10 = 1
So 100349-05-1 is a valid CAS Registry Number.

Active site mapping of porcine liver esterase (PLE) and porcine pancreatic lipase (PPL): Stereo and regiochemical outcome of hydrolysis of conformationally constrained esters

Basak,Rudra,Ghosh,Bhattacharya

, p. 974 - 980 (2007/10/03)

The regio and stereoselectivity of PLE and PPL-catalyzed hydrolysis of a number of conformationally constrained substrates have been studied. The results are discussed based on the existing active site models for the two enzymes.

A STEREOCONTROLLED SYNTHESIS OF 3-(1'-HYDROXYETHYL)-2-AZETIDINONES THROUGH TRIMETHYLSILYL TRIFLUOROMETHANESULPHONATE CATALYZED CONDENSATION OF SILYL KETENE ACETAL DERIVED FROM ETHYL 3-HYDROXYBUTYRATE AND IMINE

Guanti, Giuseppe,Narisano, Enrica,Banfi, Luca

, p. 4335 - 4338 (2007/10/02)

The silyl ketene acetal 2, prepared from ethyl 3-hydroxybutyrate, reacted with benzylidene aniline in the presence of trimethylsilyl trifluoromethanesulphonate to furnish in satisfactory yield the β-amino ester 3 as a single diastereomer, which was subseq

Stereoselective Synthesis of 3-(1-Hydroxyethyl)-2-azetidinones from 3-Hydroxybutyrates

Georg, Gunda I.

, p. 3779 - 3782 (2007/10/02)

Addition of dianions of 3-hydroxybutyrates to benzylideneaniline result in direct formation of trans S*-3-(1-hydroxyethyl)-1,4-diphenyl-2-azetidinone with 95percent diastereoselectivity.Inversion of the configuration at Cα gives the
