121259-83-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121259-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,5 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121259-83:
(8*1)+(7*2)+(6*1)+(5*2)+(4*5)+(3*9)+(2*8)+(1*3)=104
104 % 10 = 4
So 121259-83-4 is a valid CAS Registry Number.

MECHANISM OF THE REACTION OF OZONE WITH PHENOLS
Konstantinova, M. L.,Razumovskii, S. D.,Zaikov, G. E.
, p. 271 - 275 (1991)
An investigation has been carried out into the composition of the products of the O3 reaction with PhOH in different solvents and into the kinetics of their build-up.A scheme is proposed for the reaction in which the first stage, which limits the rate of
