54299-23-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54299-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,9 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54299-23:
(7*5)+(6*4)+(5*2)+(4*9)+(3*9)+(2*2)+(1*3)=139
139 % 10 = 9
So 54299-23-9 is a valid CAS Registry Number.

STEREOSELECTIVE SYNTHESIS OF (+/-)-threo-2-AMINO-1-(4-NITROPHENYL)-1,3-PROPANEDIOL

Cervinka, Otakar,Dudek, Vaclav,Fabryova, Anna,Kolar, Jiri,Lukac, Juraj,et al.

, p. 2748 - 2752 (2007/10/02)

Addition of hypobromic acid to styrene afforded styrene bromohydrin (I) which was dehydrated to ω-bromostyrene (II).Prince reaction of II with aqueous formaldehyde gave 5-bromo-4-phenyl-1,3-dioxane (III).The bromine atom in III was replaced with amino group by treatment with methanolic ammonia at 150 deg C and 6 - 8 MPa and the obtained threo-5-amino-4-phenyl-1,3-dioxane (IVa) was hydrolyzed to give (+/-)-threo-2-amino-1-phenyl-1,3-propanediol (V).Suitably chosen method of nitration converted the free base IVa or its N-acetyl derivative IVb into 5-amino-4-(4-nitrophe nyl)-1,3-dioxane (VIa) or its N-acetyl derivative VIb which without isolation were hydrolyzed to threo-2-amino-1-(4-nitrophenyl)-1,3-propanediol (VII), isolated as hydrochloride.The liberated base was resolved into enantiomers and dichloroacetylated in the known manner to give D-(-)-threo-2-dichloroacetylamino-1-(4-nitrophenyl)-1,3-propanediol (chloramphenicol).
