Check Digit Verification of cas no

The CAS Registry Mumber 140874-26-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,7 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140874-26:
(8*1)+(7*4)+(6*0)+(5*8)+(4*7)+(3*4)+(2*2)+(1*6)=126
126 % 10 = 6
So 140874-26-6 is a valid CAS Registry Number.

Enantioselective Synthesis of 3-Amino-2-azetidinones via the Ester Enolate-Imine Condensation

Steen, Fred H. van der,Kleijn, Henk,Britovsek, George J. P.,Jastrzebski, Johann T. B. H.,Koten, Gerard van

, p. 3906 - 3916 (2007/10/02)

Three approaches to the enantioselective synthesis of 3-amino-4-substituted-2-azetidinones by condensation of α-amino ester enolates with imines are described: (i) application of chiral ester derivatives of N,N-diethylglycine; (ii) application of chiral N
