Check Digit Verification of cas no

The CAS Registry Mumber 135509-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,5,0 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135509-94:
(8*1)+(7*3)+(6*5)+(5*5)+(4*0)+(3*9)+(2*9)+(1*4)=133
133 % 10 = 3
So 135509-94-3 is a valid CAS Registry Number.

Flash vacuum thermolysis of 5-(1-chloroethenyl)acenaphthene. A short synthesis of pyracylene and its bechaviour under high temperature conditions

Sarobe, Martin,Flink, Simon,Jenneskens, Leonardus W.,Zwikker, Jan W.,Wesseling, Jolanda

, p. 2125 - 2132 (2007/10/03)

Flash vacuum thermolysis (FVT) of 5-(1-chloroethenyl)acenaphthene (4) has been found to give rise to pyracylene (1).Pure 1 can be isolated from the 1100 deg C pyrolysate by recrystallization at -20 deg C.The temperature conversion data reveal that 1 decomposes and rearranges at T 1000 deg C; acenaphthylene (11), 1-ethynyl- (23) and 3-ethynyl-acenaphthylene (24) have been identified.The formation of 23 and 24 indicates that 1 rearranges to the transient cyclopentacenaphthylene (20) via a single ring-contraction-ring-expansion mechanism under FVT conditions.The experimental data are supported by semiempirical AM1 calculations of the C14H8 potential energy surface.

Flash Vacuum Pyrolysis of Phenanthrene-3,4-dicarboxylic Anhydride and Cyclobutaphenanthrene-1,2-dione: Products of Ring Contraction, Insertion and Ring Cleavage

Adeney, Michael,Brown, Roger F. C.,Coulston, Karen J.,Eastwood, Frank W.,James, Ian W.

, p. 967 - 980 (2007/10/02)

Flash vacuum pyrolysis of phenanthrene-3,4-dicarboxylic anhydride and cyclobutaphenanthrene-1,2-dione (860-70 degree/0.02-0.04 mm) gave a pyrolysate containing 1-ethynylacenaphthylene, 3-ethynylacenaphthylene and phenanthrene.The identity of the two ethynes was confirmed by synthesis.The results are interpreted in terms of a reaction sequence involving aryne formation, ring contraction, carbene insertion and ring cleavage of a highly strained intermediate.
