Check Digit Verification of cas no

The CAS Registry Mumber 111560-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,5,6 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111560-65:
(8*1)+(7*1)+(6*1)+(5*5)+(4*6)+(3*0)+(2*6)+(1*5)=87
87 % 10 = 7
So 111560-65-7 is a valid CAS Registry Number.

Synthesis and structures of isomerically pure bis-(alkylbenzo) crown ethers

Sachleben, Richard A.,Bryan, Jeffrey C.,Lavis, Jerome M.,Starks, Courtney M.,Burns, John H.

, p. 13567 - 13582 (2007/10/03)

A convenient method for the synthesis of bis-(4-alkyl-2-hydroxyphenoxy) alkoxy ethers, precursors to highly lipophilic, alkylbenzo-substituted crown ethers, is described. Thirteen isomerically-pure, bis-t-alkylbenzo crown ethers were prepared. The solid-state structures of three representative, bis-t-octylbenzo crown ethers are reported, representing the first structures ever reported for t-octylbenzocrown ethers.
