Check Digit Verification of cas no

The CAS Registry Mumber 440084-59-3 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, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 440084-59:
(8*4)+(7*4)+(6*0)+(5*0)+(4*8)+(3*4)+(2*5)+(1*9)=123
123 % 10 = 3
So 440084-59-3 is a valid CAS Registry Number.

Use of a sterically demanding Lewis acid to direct ring expansion of monoactivated methylenecyclopropanes

Taillier, Catherine,Bethuel, Yann,Lautens, Mark

, p. 8469 - 8477 (2007)

A novel synthetic route for the preparation of functionalized alkylidene pyrrolidines via a MAD/n-Bu4NI-mediated ring expansion of monoactivated MCP was developed. The substrate scope for this reaction was found to be broad for a variety of ald

Divergent selectivity in Mgl2-mediated ring expansions of methylenecyclopropyl amides and imides

Lautens, Mark,Han, Wooseok

, p. 6312 - 6316 (2007/10/03)

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
