Check Digit Verification of cas no

The CAS Registry Mumber 194302-50-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,3,0 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 194302-50:
(8*1)+(7*9)+(6*4)+(5*3)+(4*0)+(3*2)+(2*5)+(1*0)=126
126 % 10 = 6
So 194302-50-6 is a valid CAS Registry Number.

Stereoselective synthesis of cyclopropane-1,2-bis(glycine) derivatives

Neset, Siren,Hope, Hakon,Undheim, Kjell

, p. 10459 - 10470 (2007/10/03)

Conformationally constrained bis(glycines) as trans derivatives of cyclopropane have been prepared in stereoselective syntheses. (S)-4-Benzyl-2-oxazolidinone was used as a chiral auxiliary, trisyl azide was the electrophilic source of amine nitrogen. Four stereogenic centers were created. A related cis-cyclopropane derivative suffered ring closure with formation of a bicyclo[3.1.0]hex-3-one derivative. X-ray data for the latter and for (1S,2S)-1,2-bis{(1S)-azido-2-oxo-2[(4S)-benzyl-2-oxo-3-oxazolidinyl] -ethyl}cyclopropane are presented.
