Check Digit Verification of cas no
The CAS Registry Mumber 6742-26-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6742-26:
(6*6)+(5*7)+(4*4)+(3*2)+(2*2)+(1*6)=103
103 % 10 = 3
So 6742-26-3 is a valid CAS Registry Number.

Construction of Polycyclic β-Ketoesters Using a Homoconjugate Addition/Decarboxylative Dieckmann Annulation Strategy
Chen, Zhiwei,Hong, Allen Y.,Linghu, Xin
, p. 6225 - 6234 (2018/05/29)
The construction of arene-fused cyclic β-ketoesters from 2-iodoaryl esters and 1,1-cyclopropane diesters is detailed. The synthetic method takes advantage of a CuI·SMe2-mediated homoconjugate addition followed by a decarboxylative Dieckmann cyclization to afford valuable polycyclic building blocks. Various iodoaryl esters and 1,1-cyclopropane diesters were evaluated, and the limitations of both reactions are discussed. Several mechanistic probes are detailed and synthetic applications are described.
