134539-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134539-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,3 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134539-98:
(8*1)+(7*3)+(6*4)+(5*5)+(4*3)+(3*9)+(2*9)+(1*8)=143
143 % 10 = 3
So 134539-98-3 is a valid CAS Registry Number.

Chemistry of singlet oxygen. Dye-sensitized photooxygenation of arylallenes
Erden,Martinez
, p. 1859 - 1862 (2007/10/02)
1-Arylallenes react with singlet oxygen via 1,2-and 1,4-cycloaddition modes giving rise to three types of carbonyl fragments. 1,1-Diphenyl- and 1-phenylallenes react predominantly by the 1,4-mode. Plausible mechanisms are discussed for the formation of the observed products.
