Check Digit Verification of cas no

The CAS Registry Mumber 1254361-97-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,3,6 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1254361-97:
151 % 10 = 1
So 1254361-97-1 is a valid CAS Registry Number.

Facile and highly enantioselective synthesis of (+)- and (-)-fluvastatin and their analogues

Zacharia, James T.,Tanaka, Takanori,Hayashi, Masahiko

supporting information; experimental part, p. 7514 - 7518 (2011/02/22)

A highly enantioselective synthesis of (+)- and (-)-fluvastatin and their analogues has been facilitated by the reaction of an aldehyde with diketene in the presence of Ti(O-i-Pr)4 and a chiral Schiff base ligand. Either enantiomer of the Schiff base could be employed to obtain (+)- or (-)-fluvastatin. Diastereoselective reductions of the resultant keto moiety of β-hydroxy ketoesters provided the syn-1,3-diol esters (91% ee), which were subsequently recrystallized and saponified to afford (+)- and (-)-fluvastatin in >99.9% ee.
