5223-58-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5223-58-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,2 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5223-58:
(6*5)+(5*2)+(4*2)+(3*3)+(2*5)+(1*8)=75
75 % 10 = 5
So 5223-58-5 is a valid CAS Registry Number.

Secondary isotope effects in dioxirane epoxidations. Concerted or step-wise mechanism?
Angelis, Yiannis,Zhang, Xiaojun,Orfanopoulos, Michael
, p. 5991 - 5994 (2007/10/03)
The inverse α- and β-secondary isotope effects found for the epoxidation reaction of dimethyl dioxirane (DMD) with alkenes support a non polar concerted mechanism.
