1613733-72-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1613733-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,3,7,3 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1613733-72:
(9*1)+(8*6)+(7*1)+(6*3)+(5*7)+(4*3)+(3*3)+(2*7)+(1*2)=154
154 % 10 = 4
So 1613733-72-4 is a valid CAS Registry Number.

PROCESS FOR THE ENANTIOMERIC ENRICHMENT OF DIARYLOXAZOLINE DERIVATIVES

-

Page/Page column 26, (2014/07/07)

The present invention concerns a process for the manufacture of the S-enantiomer of a compound of formula (I) wherein the variables are as defined in the specification and claims, comprising the steps of (A) separating a racemic compound of formula (II) wherein R', R and R' and Y are as defined above and Z is Q; or is halogen, amino, carboxy (-COOH); into the enantiomers and collecting the S-enantiomer; (B) if Z is other than Q, converting the S-enantiomer of formula (II) from step (A) to a S- enantiomer of formula (I); (C) racemizing the R-enantiomer of formula (II) from step (A) in a reaction medium comprising a base and an aprotic organic solvent at a temperature of from 30°C to 150°C, and (D) subjecting the racemate from step (C) to a further manufacturing cycle comprising step (A) and optionally (B). Accordingly, a cyclic process is provided, wherein the undesired enantiomer of a first enantiomer separation step is racemized and then phased in a further enantiomer separation step.
