Check Digit Verification of cas no

The CAS Registry Mumber 115319-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,3,1 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 115319-79:
(8*1)+(7*1)+(6*5)+(5*3)+(4*1)+(3*9)+(2*7)+(1*9)=114
114 % 10 = 4
So 115319-79-4 is a valid CAS Registry Number.

Metalation of Phenols. Synthesis of Benzoquinones by the Oxidative Degradation Approach

Saa, Jose M.,Llobera, Antonia,Garcia-Raso, Angel,Costa, Antonio,Deya, Pedro M.

, p. 4263 - 4273 (1988)

In a effort to explore the potential of so-called oxidative degradation approach for the synthesis of quinones, we have investigated the direct metalation of a number of simple phenols such as o- and p-hydroxybenzyl alcohols, benzyl methyl ethers and N,N-dimethylbenzylamines.Apparently, only those phenolic substrates having available both a coordinating group for chelation and an electron-withdrawing group in a 1,3-relationship are efficiently lithiated, by the action of n-BuLi, in a regioselective manner.Those positions on the aromatic nucleus just flanked by a coordinating, or an acid-base, group could be metalated by action of the t-BuLi/THP system, in favorable cases.
