57074-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57074-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,7 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57074-05:
(7*5)+(6*7)+(5*0)+(4*7)+(3*4)+(2*0)+(1*5)=122
122 % 10 = 2
So 57074-05-2 is a valid CAS Registry Number.

A formal total synthesis of salvadione
Maier, Martin E.,Bayer, Alexander
, p. 4034 - 4043 (2007/10/03)
The tricyclic 6-7-6 core structure of the triterpene salvadione (1) was obtained in an efficient manner from the aryl bromide 16 and the alkyl iodide 35 carrying a methylenecyclohexane group at the terminus. Alkylation of the anion derived from 16 with th
