83086-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83086-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,8 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83086-16:
(7*8)+(6*3)+(5*0)+(4*8)+(3*6)+(2*1)+(1*6)=132
132 % 10 = 2
So 83086-16-2 is a valid CAS Registry Number.

SYNTHESIS OF PYRENE DERIVATIVES
Chaikovskii, V. K.,Novikov, A. N.
, p. 1350 - 1352 (2007/10/02)
The direct iodination of pyrene with the I2-HIO3-H2SO4 system gives a mixture of 1,6- and 1,8-diiodopyrenes with a preponderance of 1,6-diiodopyrene.Increase in the reaction temperature to 100 deg C leads to an increase in the yield of the second isomer.I
