439600-06-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 439600-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,6,0 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 439600-06:
(8*4)+(7*3)+(6*9)+(5*6)+(4*0)+(3*0)+(2*0)+(1*6)=143
143 % 10 = 3
So 439600-06-3 is a valid CAS Registry Number.

Beyond the Roger Brown rearrangement: Long-range atom topomerization in conjugated polyynes
Mabry, John,Johnson, Richard P.
, p. 6497 - 6501 (2007/10/03)
Long-range carbon atom topomerization in a 1,3-diyne has been demonstrated for the first time. 1-Phenyl-4-p-tolyl-1,3-butadiyne, 13C-enriched at C-1, was synthesized and subjected to flash vacuum pyrolysis. At 800 °C and 0.01 Torr, this resulte
