132273-93-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132273-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,7 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 132273-93:
(8*1)+(7*3)+(6*2)+(5*2)+(4*7)+(3*3)+(2*9)+(1*3)=109
109 % 10 = 9
So 132273-93-9 is a valid CAS Registry Number.

Diastereoselective addition of chiral aliphatic imines and 2-alkyl-1,3-oxazolidines to organometallic reagents

Higashiyama,Fujikura,Takahashi

, p. 722 - 728 (2007/10/02)

The reaction of organocerium reagents with chiral aliphatic imines derived from (R)-O-methylphenylglycinol afforded the corresponding amines with high diastereoselectivity. In contrast, the reaction of Grignard reagents with chiral 2-alkyl-1,3-oxazolidines derived from (R)-N-methylphenylglycinol afforded the amines with changeover in diastereoselectivity.

The absolute configuration and stereoselective Grignard reaction of N-substituted 4-phenyl-1,3-oxazolidines
