1268685-40-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268685-40-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,6,8 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1268685-40:
(9*1)+(8*2)+(7*6)+(6*8)+(5*6)+(4*8)+(3*5)+(2*4)+(1*0)=200
200 % 10 = 0
So 1268685-40-0 is a valid CAS Registry Number.

Decarbonylative cycloaddition of phthalic anhydrides with allenes
Ochi, Yosuke,Kurahashi, Takuya,Matsubara, Seijiro
, p. 1374 - 1377 (2011)
The decarbonylative cycloadditions of phthalic anhydrides with allenes were performed by using nickel catalyst. The asymmetric variant of the cycloaddition was also achieved by using chiral phosphine ligands to provide δ-lactones enantioselectively.
