Check Digit Verification of cas no
The CAS Registry Mumber 56598-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,9 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 56598-53:
(7*5)+(6*6)+(5*5)+(4*9)+(3*8)+(2*5)+(1*3)=169
169 % 10 = 9
So 56598-53-9 is a valid CAS Registry Number.

Direct Transformation of Esters into Arenes with 1,5-Bifunctional Organomagnesium Reagents

supporting information, p. 12163 - 12166 (2015/10/12)
A direct transformation of carboxylic acid esters into arenes with 1,5-bifunctional organomagnesium reagents is described. This efficient and practical method enables the one-step defunctionalization of various carboxylic acid esters to prepare benzene, anthracene, tetracene, and pentacene derivatives. A double nucleophilic addition of the 1,5-organodimagnesium reagent to the ester is followed by an immediate 1,4-elimination reaction that leads to the direct [5+1] formation of a new aromatic ring.
