109453-49-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109453-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,5 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109453-49:
(8*1)+(7*0)+(6*9)+(5*4)+(4*5)+(3*3)+(2*4)+(1*9)=128
128 % 10 = 8
So 109453-49-8 is a valid CAS Registry Number.

A Convenient One-Pot Conversion of N-Protected Amino Acids and Peptides into Alcohols

Kokotos, George

, p. 299 - 301 (1990)

N-Protected amino acids and peptides are converted to alcohols by chemoselective reduction of their corresponding mixed anhydrides with sodium borohydride in tetrahydrofuran with dropwise addition of methanol.

Ecological base-conditioned preparation of dipeptides using unprotected α-amino acids containing hydrophilic side chains

Ezawa, Tetsuya,Jung, Seunghee,Kawashima, Yuya,Noguchi, Takuya,Imai, Nobuyuki

, p. 689 - 696 (2017/07/22)

The coupling reactions of 3-phenylpropanoic acid and Ncarboxybenzyl á-amino acids with unprotected á-amino acids containing hydrophilic side chains such as aliphatic alcohol, aromatic alcohol, thiol, carboxylic acid, and amide afforded the corresponding amides in 6696% yield without racemization via the corresponding mixed carbonic carboxylic anhydrides under basic conditions through an ecological green synthetic method.

Double axial chirality promoted asymmetric [2,3] Stevens rearrangement of N-cinnamyl l-alanine amide-derived ammonium ylides

Tayama, Eiji,Naganuma, Noriko,Iwamoto, Hajime,Hasegawa, Eietsu

supporting information, p. 6860 - 6862 (2014/06/23)

The base-induced asymmetric [2,3] Stevens rearrangement of N-cinnamyl tetraalkylammonium ylides derived from l-alanine amides proceeds via a double axially chiral intermediate to afford the corresponding α-substituted alanine derivatives with high enantio- and diastereoselectivities. the Partner Organisations 2014.
