Check Digit Verification of cas no

The CAS Registry Mumber 147228-37-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,2,2 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 147228-37:
(8*1)+(7*4)+(6*7)+(5*2)+(4*2)+(3*8)+(2*3)+(1*7)=133
133 % 10 = 3
So 147228-37-3 is a valid CAS Registry Number.

Preparation method of 3-aminopropanol or 3-aminopropionic acid derivative

-

Paragraph 0229; 0241; 0242; 0245, (2018/10/11)

The invention provides a preparation method of an optically active 3-aminopropanol or 3-aminopropionic acid derivative, and belongs to the technical field of organic synthesis. A compound having a structure as shown in a formula II and a formula III is used as a raw material, and the optically active 3-aminopropanol or 3-aminopropionic acid derivative is obtained through four basic steps, namely dehydration condensation, hydrogenation reduction, reduction and hydrolysis. The raw materials adopted in the preparation method are easy to obtain and low in cost; as a chiral phosphine-transitional metal catalyst is used in the hydrogenation reduction reaction, the optically active 3-aminopropanol or 3-aminopropionic acid derivative is efficient, high in selectivity, low in cost and suitable forlarge-scale production. Compared with existing chemical resolution and chiral introduction, the asymmetric hydrogenation synthesis method provided by the invention only produces one chiral product, ishigh in yield, and has relatively high advantages in economy and raw material utilization rate.

Candida antarctica lipase B-catalyzed ring opening of 4-arylalkyl-substituted β-lactams

Tasnadi, Gabor,Forro, Eniko,Fueloep, Ferenc

, p. 2841 - 2844 (2008/03/28)

The Lipolase-catalyzed ring opening of racemic 4-benzyl- 3 and 4-phenylethyl-2-azetidinone 4 was performed with 0.5 equiv of H2O in diisopropyl ether at 45 °C. The resulting (S)-β-amino acid 5 or 6 (ee ≥ 87%) and (R)-β-lactam 7 or 8 (ee >99%) enantiomers could easily be separated. The ring opening of enantiomeric β-lactams with 18% aqueous HCl afforded the corresponding enantiopure β-amino acid hydrochlorides 9 and 10 (ee >99%).

104. The enantioselective synthesis of β-amino acids, their α-hydroxy derivatives, and the N-terminal components of bestatin and microginin

Jefford, Charles W.,McNulty, James,Lu, Zhi-Hui,Wang, Jian Bo

, p. 1203 - 1216 (2007/10/03)

L-Aspartic acid by tosylation, anhydride formation, and reduction with NaBH4 was converted into (3S)-3-(tosylamino)butan-4-olide (8; Scheme 1). Treatment of 8 with ethanolic trimethylsilyl iodide gave the N-protected deoxy-iodo-β-homoserine ethyl ester 9. The latter, on successive nucleophilic displacement with lithium dialkylcuprates (→ 10a-e), alkaline hydrolysis (→ 11a-e), and reductive removal of the tosyl group, produced the corresponding 4-substituted (3R)-3-aminobutanoic acids 12a-e (ee >99%). Electrophilic hydroxylation of 8 (→ 19; Scheme 3), subsequent iodo-esterification (→ 21; Scheme 4), and nucleophilic alkylation and phenylation afforded, after saponification and deprotection, a series of 4-substituted (2S,3A)-3-amino-2-hydroxybutanoic acids 24 including the N-terminal acids 24e (= 3) and 24f (= 4) of bestatin and microginin (de >95%), respectively.
