139192-68-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139192-68-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,9 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139192-68:
(8*1)+(7*3)+(6*9)+(5*1)+(4*9)+(3*2)+(2*6)+(1*8)=150
150 % 10 = 0
So 139192-68-0 is a valid CAS Registry Number.

The geometric parameters of the title compound, (2S)-2-[(2R,4S)-4-phenyl-3-tosyl-1,3-oxazolidin-2-yl] cyclo-pentanone, C21H23NO4S, are in good agreement with other arylsulfonyl-oxazolidines. While the oxazolidine ring displays an envelope conformation, the cyclopentanone ring has a twist conformation.
