82898-92-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82898-92-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,9 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82898-92:
(7*8)+(6*2)+(5*8)+(4*9)+(3*8)+(2*9)+(1*2)=188
188 % 10 = 8
So 82898-92-8 is a valid CAS Registry Number.

Stereoselective Synthesis of Alcohols, XI. Double Stereodifferentiation in the Addition of Crotylboronates to Aldehydes: Prelog-Djerassi Lactone

Hoffmann, Reinhard W.,Zeiss, Hans-Joachim,Ladner, Wolfgang,Tabche, Susanne

, p. 2357 - 2370 (2007/10/02)

Addition of the (Z)-crotylboronate 11 to (S)-(+)-α-methylbutyraldehyde (4) resulted in the Cram and Anti-Cram diastereomers 6 and 7.Their ratio depended on the chirality of the boronate component.Hence the formation of the alcohol 7 could be favoured by double stereodifferentiation.Similarly, on addition of the (E)-crotylboronate 12 predominant formation of the isomer 13 could be achieved.These observations formed the basis for a stereoselective synthesis of the Prelog-Djerassi lactone 3.
