Check Digit Verification of cas no
The CAS Registry Mumber 116529-61-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,2 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116529-61:
(8*1)+(7*1)+(6*6)+(5*5)+(4*2)+(3*9)+(2*6)+(1*1)=124
124 % 10 = 4
So 116529-61-4 is a valid CAS Registry Number.

An "ortho effect" in electrophilic aromatic nitrations: Theoretical analysis and experimental validation

Usually, a π-donor substituent acts as an ortho/para directing group in an electrophilic aromatic substitution reaction, and a π-acceptor substituent acts as a meta directing group. Interestingly, when a π-acceptor substituent is meta to a π-donor substituent, certain electrophilic aromatic nitration occurs ortho to the π-acceptor substituent rather than para . The "ortho effect", highlighted in various textbooks, has been tentatively analyzed here based on ab initio calculations. The reliability of the calculations was verified by the corresponding experimental data, including a newly-designed electrophilic aromatic nitration that also gave reasonable product distributions.
