228251-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228251-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,2,5 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 228251-02:
(8*2)+(7*2)+(6*8)+(5*2)+(4*5)+(3*1)+(2*0)+(1*2)=113
113 % 10 = 3
So 228251-02-3 is a valid CAS Registry Number.

Diastereoselective addition of radicals to chiral 1,3-dioxin-4-ones
Graalfs, Heiner,Froehlich, Roland,Wolff, Christian,Mattay, Jochen
, p. 1057 - 1073 (1999)
Intermolecular addition of radicals to the 1,3-dioxin-4-ones 1a,b and 2a,b with (-)-menthone incorporated as chiral auxiliary in 2-position were investigated. Photochemically generated radicals from 1,3-dioxolane, oxolane, and 2-propanol were added with h
