Check Digit Verification of cas no

The CAS Registry Mumber 216759-93-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,7,5 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 216759-93:
(8*2)+(7*1)+(6*6)+(5*7)+(4*5)+(3*9)+(2*9)+(1*3)=162
162 % 10 = 2
So 216759-93-2 is a valid CAS Registry Number.

Bridging of resorcin[4]arenes in the chair conformation to cavitands having two pairs of axial and equatorial substituents

Middel, Oskar,Verboom, Willem,Hulst, Ron,Kooijman, Huub,Spek, Anthony L.,Reinhoudt, David N.

, p. 8259 - 8265 (1998)

Cavitands 18-22 were prepared in 29-90% yield by bridging of the chair- methylresorcin[4]arenes 3-7 with bromochloromethane. According to X-ray analysis of cavitand 19 and 1-D and 2-D NMR spectroscopy for 18, the cavitands possess a stereochemistry with t
