65794-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65794-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,7,9 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 65794-42:
(7*6)+(6*5)+(5*7)+(4*9)+(3*4)+(2*4)+(1*2)=165
165 % 10 = 5
So 65794-42-5 is a valid CAS Registry Number.

, (2008/06/13)

There is provided a process for the preparation of an enantiomer of a compound of formula (I) which process comprises separation thereof from a mixture of diastereoisomers of a compound of the formula (I): STR1 wherein R is acetyl, α-hydroxyethyl or a protected derivative thereof, and R1 and R2 are substituted or unsubstituted hydrocarbon groups, or are joined so as to form a carbocyclic or heterocyclic ring; at least one of R1 and R2 containing a chiral center, such that the enantiomer can be separated thereby; and R3 and R4 are independently hydrogen or an organic group bonded via a carbon atom to the tetrahydro-oxazine ring, or R3 and R4 are joined so as to form together with the carbon atom to which they are attached an optionally substituted C3-7 cycloalkyl or optionally substituted heterocyclyl ring. The enantiomer is of use in the preparation of optically active carbapenem antibiotics.
