Check Digit Verification of cas no
The CAS Registry Mumber 4235-05-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,3 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4235-05:
(6*4)+(5*2)+(4*3)+(3*5)+(2*0)+(1*5)=66
66 % 10 = 6
So 4235-05-6 is a valid CAS Registry Number.

Synthesis of 1-(2-ethynyl-6-methylphenyl)- and 1-(2-ethynyl-6-methoxyphenyl)-naphthalene and their cyclization
Storch, Jan,?ermák, Jan,Karban, Jind?ich
, p. 6814 - 6816 (2008/03/12)
A Suzuki cross-coupling reaction of hindered 2-bromo-1-trimethylsilylethynylbenzenes with 1-naphthaleneboronic acid yielding (2-ethynylphenyl)naphthalenes has been achieved. Their subsequent cyclization was carried out, giving benzo[c]phenanthrenes, without the use of photochemical procedures.
