81425-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81425-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,2 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81425-40:
(7*8)+(6*1)+(5*4)+(4*2)+(3*5)+(2*4)+(1*0)=113
113 % 10 = 3
So 81425-40-3 is a valid CAS Registry Number.

CYCLOADDITIONS DES ARSOLES A HAUTE TEMPERATURE
Sennyey, Gerard,Mathey, Francois
, p. 4713 - 4716 (2007/10/02)
At room temperature 1-phenyl-2,5-dimethylarsole 1 gives cycloadditions with dienophiles whereas at 160 deg C it yields arsenic atoms which react with tolane to give the 1,4-diarsabicyclooctatriene 8 ; 1,2,5-triphenylarsole 2 is less reactive a
