Check Digit Verification of cas no

The CAS Registry Mumber 146400-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,4,0 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146400-42:
(8*1)+(7*4)+(6*6)+(5*4)+(4*0)+(3*0)+(2*4)+(1*2)=102
102 % 10 = 2
So 146400-42-2 is a valid CAS Registry Number.

Intramolecular Cyclopropanation: Stereospecific Synthesis of (E)- and (Z)-1-Aminocyclopropane-1-carboxylic Acids

Koskinen, Ari M. P.,Munoz, Luis

, p. 879 - 886 (2007/10/02)

tert-Butyl-substituted allyl malonates, prepared in two steps from malonic acid, are diazotized in high yields.The diazomalonates 7 undergo a stereospecific copper(I)-catalyzed cyclopropanation to give 1-(tert-butoxycarbonyl)-3-oxa-2-oxobicyclohexanes 8 which can be converted to the protected (E)- or (Z)-1-aminocyclopropane-1-carboxylic acids 10 or 15 via Curtius- or Hoffmann-type rearrangements, respectively.The sequences are short (six steps from malonic acid) and proceed with good overall yields (20-40percent overall from malonic acid).The free amino acids 12 and 13 can be liberated in two steps.
