The CAS Registry Mumber 1253646-05-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,6,4 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1253646-05:
(9*1)+(8*2)+(7*5)+(6*3)+(5*6)+(4*4)+(3*6)+(2*0)+(1*5)=147
147 % 10 = 7
So 1253646-05-7 is a valid CAS Registry Number.

The enantioselective synthesis of (R)- and (S)-3-amino-3,4-dihydro-1H-[1,8] naphthyridin-2-one

Londregan, Allyn T.,Bernhardson, David,Bradow, James,Makowski, Teresa M.,Storer, Gregory,Warmus, Joseph,Wooten, Ceshea,Yang, Xiaojing

, p. 2072 - 2075 (2010)

A number of approaches to the enantioselective synthesis of (R)- and (S)-3-amino-3,4-dihydro-1H-[1,8]naphthyridin-2-one were studied. A novel one-pot asymmetric reduction/lactamization provided the desired products in high yield and enantiomeric excess.
