Check Digit Verification of cas no
The CAS Registry Mumber 2133-35-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2133-35:
(6*2)+(5*1)+(4*3)+(3*3)+(2*3)+(1*5)=49
49 % 10 = 9
So 2133-35-9 is a valid CAS Registry Number.

-
, (2008/06/13)
There is disclosed a method for producing an essentially enantiomerically pure N-protected-azetidine-2-carboxylic acid of formula (1): which method is characterized by: subjecting a crude enantiomerically excess N-protected-azetidine-2-carboxylic acid comprising said enantiomer represented by formula (1) in excess to the other enantiomer thereof to crystallization in an organic solvent selected from aromatic hydrocarbon, aliphatic ether, aliphatic alcohol, aliphatic ketone, aliphatic nitrile, aliphatic amide, aliphatic sulfoxide, aliphatic ester and a mixed solvent thereof, wherein R is: an optionally substituted alkyl, alicyclic or alicyclicalkyl group, an optionally substituted alkenyl group, an optionally substituted aryl group, an optionally substituted heteroaryl group, or a dialkylamino group, and absolute configuration of the asterisked asymmetric carbon atom is S or R.
