Check Digit Verification of cas no
The CAS Registry Mumber 868860-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,8,8,6 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 868860-20:
(8*8)+(7*6)+(6*8)+(5*8)+(4*6)+(3*0)+(2*2)+(1*0)=222
222 % 10 = 2
So 868860-20-2 is a valid CAS Registry Number.

A new protocol for the synthesis of 4,7,12,15-tetrachloro[2.2]paracyclophane

We report a green and convenient protocol to prepare 4,7,12,15-tetrachloro[2.2]paracyclophane, the precursor of parylene D, from 2,5-dichloro-p-xylene. In the first bromination step, with H2O2-HBr as a bromide source, this procedure becomes organic-waste-free and organic-solvent-free and can appropriately replace the existing bromination methods. The Winberg elimination-dimerization step, using aqueous sodium hydroxide solution instead of silver oxide for anion exchange, results in a significant improvement in product yield. Furthermore, four substituted [2.2]paracyclophanes were also prepared in this convenient way.
