Check Digit Verification of cas no

The CAS Registry Mumber 871210-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,2,1 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 871210-05:
(8*8)+(7*7)+(6*1)+(5*2)+(4*1)+(3*0)+(2*0)+(1*5)=138
138 % 10 = 8
So 871210-05-8 is a valid CAS Registry Number.

FLUOROUS OXAZOLIDINONE CHIRAL AUXILIARY COMPOUNDS AND METHODS OF MANUFACTURE

-

Page/Page column 10-11; 18, (2008/06/13)

The present invention relates generally to perfluoroalkyl chiral auxiliary compounds and methods of manufacture. These compounds have the functionality to effectively support the synthesis of chiral compounds in single reactions, high-throughput parallel recations, or combinatorial reactions The invention relates to two oxazolidmone chiral auxiliaries (1) and (2): wherein Rf is a perfluoroalkyl group having the general formula (CH2)x-CyF2y+1 where x = 1-5 and y = 4-10 and wherein B is an unfunctionalized aryl, alkyl or arylalkyl group Pn a preferred embodiment, x = 2 and y = 6 and B is derived from unfunctionalized ammo acids The ammo acids may be from either the D- or L- series, and are preferably enantiomeπcally pure or in very high enantiomeric excess in either configuration.
