19139-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19139-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,3 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19139-24:
(7*1)+(6*9)+(5*1)+(4*3)+(3*9)+(2*2)+(1*4)=113
113 % 10 = 3
So 19139-24-3 is a valid CAS Registry Number.

THE PRESSURE EFFECT IN THE HOMO-DIELS-ALDER REACTION(+)
Jenner, G.,Papadopoulos, M.
, p. 4333 - 4336 (2007/10/02)
The homo-Diels-Alder reaction is accelerated by pressure to the same extent as Diels-Alder cycloadditions.On the basis of the activation volume, the establishment of the two new bonds is concluded to occur simultaneously.
