The CAS Registry Mumber 139437-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,3 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139437-53:
(8*1)+(7*3)+(6*9)+(5*4)+(4*3)+(3*7)+(2*5)+(1*3)=149
149 % 10 = 9
So 139437-53-9 is a valid CAS Registry Number.

DIASTEREOSELECTIVE ADDITION OF ORGANOMETALLIC REAGENTS TO CHIRAL IMINES AND 1,3-OXAZOLIDINES

Higashiyama, Kimio,Inoue, Hiroaki,Takahashi, Hiroshi

, p. 235 - 238 (2007/10/02)

The reaction of MeLi or MeMgBr with chiral aromatic imines and 2-aryl-1,3-oxazolidines derived from (R)-phenylglycinol afforded with good diastereoselectivity (R,R)-amines from imines, but the (R,S)-amines from 1,3-oxazolidines, respectively.
