45101-25-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 45101-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,5,1,0 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 45101-25:
(7*4)+(6*5)+(5*1)+(4*0)+(3*1)+(2*2)+(1*5)=75
75 % 10 = 5
So 45101-25-5 is a valid CAS Registry Number.

Efficient asymmetric synthesis of N-protected-β-aryloxyamino acids via regioselective ring opening of serine sulfamidate carboxylic acid

Malhotra, Rajesh,Dey, Tushar K.,Dutta, Swarup,Basu, Sourav,Hajra, Saumen

, p. 6507 - 6515 (2014/08/18)

First regioselective ring opening of serine derived cyclic sulfamidate by hard nucleophiles like ArONa is developed, where β-elimination of serine sulfamidate ester by stronger nucleophiles is overcome by reversal of the electronic effect of the carboxyla

PHOSPHORORGANISCHE VERBINDUNGEN 109 DIE SYNTHESE FLUORESZIERENDER REAGENTIEN MIT CHEMOSELEKTIVEN ANKERGRUPPEN

Horner, Leopold,Hallenbach, Werner

, p. 173 - 188 (2007/10/02)

A route for the synthesis of type B-compounds is reported.Compound 5 is a strong fluorescent and is O-selective.Type C-compounds, for example 10a to 10d show a high fluorescence and are O-selective.They are obtained via 6 and 7 (n = 2-4, 6; R = Me, X = F).Boc-serine is O-phosphonylated by the methyl-phophonicacid-esterfluorides, for example 10c. ω-(9-Acridinyl)alkyl-phosphonicacid-alkylesterfluorides, like 22, are available in only moderate yields via 15a-e as intermediates.More but unsuccesful experiments for the synthesis of fluorescent and O-selective acridine compounds are reported shortly.
