Check Digit Verification of cas no

The CAS Registry Mumber 147976-16-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,9,7 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 147976-16:
(8*1)+(7*4)+(6*7)+(5*9)+(4*7)+(3*6)+(2*1)+(1*6)=177
177 % 10 = 7
So 147976-16-7 is a valid CAS Registry Number.

Stereoselective synthesis of protected amino alkyl epoxides

Romeo, Sergio,Rich, Daniel H.

, p. 4939 - 4942 (1994)

The mechanism of epoxidation of chiral allyl amines has been investigated. The intrinsic stereoselectivity for epoxidation is shown to be approximately 5:1 and is independent of the nitrogen substituent. However, the nature of the N-protecting group influences the stability of the undesired epoxide to the acidic media, with the minor diastereomer undergoing preferential decomposition. Conditions are reported for the highly stereoselective synthesis of epoxide 9R, an important building block in the synthesis of several enzyme inhibitors.

Facile synthetic route to (2S,3S)-3-amino-2-hydroxy-4-phenylbutyric acid and its derivatives, the key intermediates for HIV protease inhibitors

Lei, Lijun,He, Xuchang,Bai, Donglu

, p. 1535 - 1540 (2007/10/03)

A facile and efficient route to (2S,3S)-3-amino-2-hydroxy-4-phenylbutyric acid and its derivative (4S,5S)-4-benzyl-5-hydroxymethyl oxazolidin-2-one is presented. N-phthaloyl protected L-phenylalanine 1 was treated with thionyl chloride followed by hydroge

Synthesis of N-BOC-3-amino-1,2-epoxy-4-phenylbutane from (3S)-hydroxy-γ-butyrolactone by means of the Hofmann rearrangement

Murakami, Masahiro,Hinoue, Kazumasa,Nakagawa, Kazuya,Monden, Yoshiko,Furukawa, Yoshiro,Katsumura, Shigeo

, p. 77 - 80 (2007/10/03)

The stereocontrolled synthesis of the title alkylaminoepoxide was achieved starting from (3S)-hydroxy-γ-butyrolactone by efficient utilization of the Hofmann rearrangement followed by intramolecular oxazolidinone ring formation as a key step.
