Check Digit Verification of cas no

The CAS Registry Mumber 1445778-71-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,5,7,7 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1445778-71:
(9*1)+(8*4)+(7*4)+(6*5)+(5*7)+(4*7)+(3*8)+(2*7)+(1*1)=201
201 % 10 = 1
So 1445778-71-1 is a valid CAS Registry Number.

Convenient synthesis of various substituted homotaurines from alk-2-enamides

Nai, Youfeng,Xu, Jiaxi

, p. 1355 - 1365 (2013/08/23)

Various substituted homotaurines (=3-aminopropane-1-sulfonic acids) 6 were readily synthesized in satisfactory to good yields via the Michael addition of thioacetic acid to alk-2-enamides 3 (→4), followed by LiAlH4 reduction (→5) and performic acid oxidation (Scheme 1). The configuration of 'anti'-disubstituted homotaurine 'anti'-6h was deduced from the 3-(acetylthio)alkanamide (=S-(3-amino-1,2-dimethyl-3-oxopropyl) ethanethioate)'anti'-4h formed in the Michael addition, which was identified via the Karplus equation analysis, and confirmed by X-ray diffraction analysis. The current route is an efficient method to synthesize diverse substituted homotaurines, including 1-, 2-, and N-monosubstituted, as well as 1,2-, 1,N-, 2,N-, and N,N-disubstituted homotaurines (Table).
