Check Digit Verification of cas no
The CAS Registry Mumber 21752-35-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,5 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21752-35:
(7*2)+(6*1)+(5*7)+(4*5)+(3*2)+(2*3)+(1*5)=92
92 % 10 = 2
So 21752-35-2 is a valid CAS Registry Number.

PROCESS FOR ENANTIOMERIC ENRICHMENT OF 2 ', 6 ' - PIPECOLOXYLIDIDE
-
Page/Page column 17, (2014/02/15)
The invention discloses a process for enantiomeric enrichment of 2',6'-pipecoloxylidide using a chiral carbamoyl benzoic acid to provide (S)-enantiomer in high yield and high enantiomeric purity. The invention also discloses novel intermediates formed in the process of enantiomeric enrichment of 2',6'-pipecoloxylidide, preparation of N- substituted amidic acids and alkylation of 2',6'-pipecoloxylidide.
