Check Digit Verification of cas no
The CAS Registry Mumber 118191-17-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,1,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 118191-17:
(8*1)+(7*1)+(6*8)+(5*1)+(4*9)+(3*1)+(2*1)+(1*7)=116
116 % 10 = 6
So 118191-17-6 is a valid CAS Registry Number.

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
