98627-62-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98627-62-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,2 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98627-62:
(7*9)+(6*8)+(5*6)+(4*2)+(3*7)+(2*6)+(1*2)=184
184 % 10 = 4
So 98627-62-4 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
