65869-81-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65869-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 65869-81:
(7*6)+(6*5)+(5*8)+(4*6)+(3*9)+(2*8)+(1*1)=180
180 % 10 = 0
So 65869-81-0 is a valid CAS Registry Number.

Steric and Electronic Substituent Effects Influencing Regioselectivity of Tetracene Endoperoxidation

Baral, Rom Nath,Thomas, Samuel W.

, p. 11086 - 11091 (2015/11/18)

This paper describes the influence of steric and electronic factors in the regioselectivity of endoperoxide formation of tetracene derivatives using 1O2. A combination of kinetics experiments and product distributions resulting from these photosensitized oxidations demonstrates that, while the steric effect of o-alkyl groups on aryl substituents is highly localized to the substituted ring, the resistance to oxidation based on phenylethynyl substituents is more evenly distributed between the two reactive rings. These results are important for the rational design of highly persistent acenes.
