20527-08-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20527-08-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,2 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20527-08:
(7*2)+(6*0)+(5*5)+(4*2)+(3*7)+(2*0)+(1*8)=76
76 % 10 = 6
So 20527-08-6 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
