Check Digit Verification of cas no
The CAS Registry Mumber 13893-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13893-45:
(7*1)+(6*3)+(5*8)+(4*9)+(3*3)+(2*4)+(1*5)=123
123 % 10 = 3
So 13893-45-3 is a valid CAS Registry Number.

Accessing d-Valine Synthesis by Improved Variants of Bacterial Cyclohexylamine Oxidase
Gong, Rui,Yao, Peiyuan,Chen, Xi,Feng, Jinhui,Wu, Qiaqing,Lau, Peter C. K.,Zhu, Dunming
, p. 387 - 390 (2018)
Chemoenzymatic deracemization was applied to prepare d-valine from racemic valine ethyl ester or l-valine ethyl ester in high yield (up to 95 %) with excellent optical purity (>99 % ee) by employing a newly evolved cyclohexylamine oxidase (CHAO) variant Y321I/M226T exhibiting catalytic efficiency that was 30 times higher than that of the wildtype CHAO. Interestingly, CHAO and its variants showed opposite enantioselectivity for valine ethyl ester and phenylalanine ethyl ester.
Stereospecific Synthesis of 3,4-Dihydro-2 H-naphtho-1,4-oxazin-2-ones by Unification of Benzoxepine-4-carboxylates with Chiral Amino Acid Ethyl Esters
Bhimapaka, China Raju,Kasagani, Veera Prasad,Kurma, Siva Hariprasad
, p. 2976 - 2983 (2020)
A novel and efficient stereocontrolled method has been developed for the preparation of chiral 3,4-dihydro-2H-naphtho[1,2-b][1,4]oxazin-2-ones by the reaction of benzoxepine-4-carboxylates with chiral amino acid ethyl esters for the first time. The chiral 3,4-dihydro-2H-naphtho-1,4-oxazinones have been achieved in one step by the formation of C-N, C-C, and C-O bonds.
A Strategy Towards the Stereoselective Synthesis of 5-Hydroxylysine
Loehr, Birgit,Orlich, Simone,Kunz, Horst
, p. 1139 - 1141 (2007/10/03)
A stereoselective synthesis of 5-hydroxylysine is described in which the α-stereogenic centre is generated by a Schoellkopf amino acid synthesis, and the ethanolamine structure is obtained via Sharpless aminohydroxylation from an olefin moiety. The reactions and their selectivities are studied.
