Check Digit Verification of cas no

The CAS Registry Mumber 1138148-73-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,1,4 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1138148-73:
(9*1)+(8*1)+(7*3)+(6*8)+(5*1)+(4*4)+(3*8)+(2*7)+(1*3)=148
148 % 10 = 8
So 1138148-73-8 is a valid CAS Registry Number.

OXAZOLIDINONE DERIVATIVE HAVING 7-MEMBERED HETERO RING

-

, (2010/08/07)

The present invention provides a novel oxazolidinone derivative of the formula (I): wherein Ring A is (A-1) a 7-membered monocyclic heterocycle containing three N atoms; (A-2) a 7-membered monocyclic heterocycle containing two N atoms and one O atom; or (A-3) a 7-membered monocyclic heterocycle containing two N atoms and one S atom, SO or SO2, wherein said monocyclic heterocycle is optionally substituted, optionally unsaturated and optionally fused with another ring; X1 is a single bond, or a heteroatom-containing group selected from the group consisting of -O-, -S-, -NR2-, -CO-, -CS-, -CONR3-, -NR4CO-, -SO2NR5-, and -NR6SO2-, wherein R2, R3, R4, R5 and R6 are independently hydrogen or lower alkyl, or lower alkylene or lower alkenylene each optionally interrupted by said heteroatom-containing group; Ring B is optionally substituted carbocycle or optionally substituted heterocycle; and R1 is hydrogen, or an organic residue which is able to bind to the 5-position of the oxazolidinone ring in oxazolidinone antimicrobial agents, pharmaceutically acceptable salts and solvates thereof which are useful as an antibacterial agent.
