Check Digit Verification of cas no

The CAS Registry Mumber 105786-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,7,8 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 105786-33:
(8*1)+(7*0)+(6*5)+(5*7)+(4*8)+(3*6)+(2*3)+(1*3)=132
132 % 10 = 2
So 105786-33-2 is a valid CAS Registry Number.

Reactions of 1-(1-Phenanthryl)pyrene Catalysed by Aluminium Chloride (Rearrangements, Cyclisations, Phenylations)

Bunte, Reinhard,Gundermann, Karl-Dietrich,Leitich, Johannes,Polansky, Oskar E.,Zander, Maximilian

, p. 247 - 250 (2007/10/02)

Under the influence of aluminium chloride plus tin tetrachloride in boiling benzene (contrary to the solvent-free system) 1-(1-phenanthryl)pyrene (2) does not form the expected product 1 of a dehydrogenating cyclisation of 2 (Scholl reaction).Instead, complete rearrangement of 2 to isomeric biaryls occurs.Besides biaryls 3 and 4, isolated products include fluoranthenes 5-7 derived from unphenylated 3 by dehydrogenating cyclisations and phenylations.
