Check Digit Verification of cas no

The CAS Registry Mumber 158252-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,2,5 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 158252-23:
(8*1)+(7*5)+(6*8)+(5*2)+(4*5)+(3*2)+(2*2)+(1*3)=134
134 % 10 = 4
So 158252-23-4 is a valid CAS Registry Number.

Esterification via acid fluoride activation

Mayer,Joullie

, p. 2367 - 2377 (1994)

The esterification of sterically hindered or non-nucleophilic alcohols may often be problematic. The reaction of alcohols with acid fluorides is reported to be superior to standard acid activation protocols frequently used for difficult esterifications. T

Synthetic studies of a constrained ring didemnin analog

Mayer,Pfizenmayer,Cordova,Li,Joullie

, p. 519 - 522 (2007/10/02)

An asymmetric Diels-Alder reaction in the presence of 3.0 M lithium perchlorate-diethyl ether was used to generate the initial stereochemistry for a cyclohexane amino acid (3), a key intermediate in the preparation of a fused ring didemnin analog. This constrained ring macrocycle should provide insight into the binding site conformation of the bioactive species.
