Check Digit Verification of cas no

The CAS Registry Mumber 957220-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,2,2 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 957220-06:
(8*9)+(7*5)+(6*7)+(5*2)+(4*2)+(3*0)+(2*0)+(1*6)=173
173 % 10 = 3
So 957220-06-3 is a valid CAS Registry Number.

Gold(I)-catalyzed [2 + 2]-cycloaddition of allenenes

Luzung, Michael R.,Mauleon, Pablo,Toste, F. Dean

, p. 12402 - 12403 (2008/09/17)

A cationic phosphinegold(I)-catalyzed intramolecular [2 + 2]-cycloaddition between an allene and an alkene to form alkylidene?cyclobutanes is described. Additionally, the reported cycloisomerization reaction provides access to enantioenriched bicyclo-[3.2.0] structures using chiral biarylphosphinegold(I) complexes as catalysts. Copyright
