1437-81-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1437-81-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1437-81:
(6*1)+(5*4)+(4*3)+(3*7)+(2*8)+(1*1)=76
76 % 10 = 6
So 1437-81-6 is a valid CAS Registry Number.

Convenient Approach to 2-Substituted (Thio)morpholin-3-ones from α-Diazoacetates via X-H Carbene Insertion – Lactamization Sequence

Solovyov, Igor,Dar'in, Dmitry,Krasavin, Mikhail

, p. 7432 - 7438 (2019/11/28)

Stepwise coupling of N-Boc-protected β-aminoethanols or β-mercaptoethylamines with various α-diazoacetates provides a new, unified approach to constructing (thio)morpholin-3-ones. The process involves a Rh2(esp)2-catalyzed X-H insert

A versatile synthesis of various substituted taurines from vicinal amino alcohols and aziridines

Chen, Ning,Jia, Weiyi,Xu, Jiaxi

experimental part, p. 5841 - 5846 (2010/03/03)

Taurine and structurally diverse substituted taurines have been synthesized by peroxyformic acid, oxidation of the thiazolidine-2-thione intermediates generated from, vicinal amino alcohols or aziridines and carbon disulfide. The stereochemistry and mechanisms of the reactions are disscussed. The method is a salt-free and versatile route, convenient in terms of purification, and can be used to synthesize optically active substituted taurines.
