902480-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 902480-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,4,8 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 902480-53:
(8*9)+(7*0)+(6*2)+(5*4)+(4*8)+(3*0)+(2*5)+(1*3)=149
149 % 10 = 9
So 902480-53-9 is a valid CAS Registry Number.

Studies toward soraphen A: An aldol-metathesis avenue to the macrocyclic framework
Vincent, Guillaume,Mansfield, Darren J.,Vors, Jean-Pierre,Ciufolini, Marco A.
, p. 2791 - 2794 (2007/10/03)
We describe a convergent approach to soraphen A, 1, that involves coupling of two fragments by an aldol condensation-olefin metathesis sequence. This route permits rapid access to congeners of 1.
