123975-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123975-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,9,7 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123975-48:
(8*1)+(7*2)+(6*3)+(5*9)+(4*7)+(3*5)+(2*4)+(1*8)=144
144 % 10 = 4
So 123975-48-4 is a valid CAS Registry Number.

Novel Resolution of Chiral Lactams
Ueroegdi, Laszlo,Kisfaludy, Lajos,Patthy, Agnes,Vezer, Csilla
, p. 133 - 134 (2007/10/02)
A practical method of resolving chiral lactams, e.g. 1, has been evolved, based on the hydroxymethylation of the lactam, followed by esterification of the product 2 with an optically active N-protected amino acid derivative, e.g.N-benzyloxycarbonylphenyla
