247585-67-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 247585-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,5,8 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 247585-67:
(8*2)+(7*4)+(6*7)+(5*5)+(4*8)+(3*5)+(2*6)+(1*7)=177
177 % 10 = 7
So 247585-67-7 is a valid CAS Registry Number.

A new approach to the core of Roseophilin
Fagan, Maria A.,Knight, David W.
, p. 6117 - 6120 (2007/10/03)
5-Endo-dig iodocyclisation of the homopropargylic sulfonamide 10 gives the iodo-dihydropyrrole 11; subsequent 5-exo-trig radical cyclisation of the derived iodopyrrole 12 followed by allylic oxidation then delivers the bicyclic core 2 of Roseophilin 1.
