Check Digit Verification of cas no
The CAS Registry Mumber 440084-60-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,0,8 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 440084-60:
(8*4)+(7*4)+(6*0)+(5*0)+(4*8)+(3*4)+(2*6)+(1*0)=116
116 % 10 = 6
So 440084-60-6 is a valid CAS Registry Number.

Divergent selectivity in Mgl2-mediated ring expansions of methylenecyclopropyl amides and imides
Lautens, Mark,Han, Wooseok
, p. 6312 - 6316 (2002)
We report a novel approach to prepare five- and six-membered heterocyclic compounds via a ring expansion of monoactivated methylenecyclopropanes (MCPs) with aldimines and aldehydes in the presence of MgI2. Monoactivated MCPs behave as homo-Mich
