Check Digit Verification of cas no

The CAS Registry Mumber 66142-79-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,4 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 66142-79:
(7*6)+(6*6)+(5*1)+(4*4)+(3*2)+(2*7)+(1*9)=128
128 % 10 = 8
So 66142-79-8 is a valid CAS Registry Number.

Selective catalytic carbanionic ethylation of methylphenols: Influence of catalyst and substitution pattern

Steele, Barry R.,Villalonga-Barber, Carolina,Micha-Screttas, Maria,Screttas, Constantinos G.

, p. 2093 - 2097 (2007/10/03)

Addition of ethylene to the carbanions formed by the metallation of the lithium salts of di- and trimethylphenols by the strongly basic system, n-BuLi-LiK(OCH2CH2NMe2)2 provides a useful synthetic route to a range of alkylphenols. The ease of alkylation of the methyl groups decreases in the order ortho>meta>para while the inclusion of Mg(OCH2CH2OEt)2 in the catalyst restricts alkylation to the methyl groups ortho to the hydroxy group. Dialkylation occurs only at the ortho-methyl groups and only if the adjacent meta-position is unsubstituted. The potential of these products for the synthesis of sterically hindered ligands is outlined.
