1313613-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313613-16-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,6,1 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1313613-16:
(9*1)+(8*3)+(7*1)+(6*3)+(5*6)+(4*1)+(3*3)+(2*1)+(1*6)=109
109 % 10 = 9
So 1313613-16-9 is a valid CAS Registry Number.

On the dimers of β-tocopherol
B?hmdorfer, Stefan,Patel, Anjan,Netscher, Thomas,Gille, Lars,Rosenau, Thomas
body text, p. 4858 - 4861 (2011/08/04)
Upon oxidation in aprotic media, β-tocopherol (2) forms a spiro-dimer (10) as the main product. The reaction mechanism is a hetero-Diels-Alder process with inverse electron demand of two intermediate ortho-quinone methide molecules. The spiro-dimer can be
