Check Digit Verification of cas no

The CAS Registry Mumber 1303559-75-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,3,5,5 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1303559-75:
(9*1)+(8*3)+(7*0)+(6*3)+(5*5)+(4*5)+(3*9)+(2*7)+(1*5)=142
142 % 10 = 2
So 1303559-75-2 is a valid CAS Registry Number.

Gold and bronsted acid catalyzed hydride shift onto allenes: Divergence in product selectivity

Bolte, Benoit,Gagosz, Fabien

supporting information; experimental part, p. 7696 - 7699 (2011/06/27)

A series of allenyl ethers can be transformed into various fused or spiro tetrahydrofurans and tetrahydropyrans following a hydride shift/cyclization sequence. A divergence in product selectivity, which depends on the nature of the catalyst used (Au(I) complex or Bronsted acid), was observed.
