Check Digit Verification of cas no
The CAS Registry Mumber 188-73-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,8 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188-73:
(5*1)+(4*8)+(3*8)+(2*7)+(1*3)=78
78 % 10 = 8
So 188-73-8 is a valid CAS Registry Number.

Synthesis of Polycyclic Aromatic Hydrocarbons
-
Paragraph 0014; 0018, (2015/01/07)
The present invention relates to the synthesis of polycyclic aromatic compounds. Compounds such as terrylene or quaterrylene may now be prepared in relatively high yield by reaction of naphthalene or perylene via Scholl-type coupling in the presence of a superacid and an oxidant in an inert solvent.
