1093430-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1093430-77-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,3,4,3 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1093430-77:
(9*1)+(8*0)+(7*9)+(6*3)+(5*4)+(4*3)+(3*0)+(2*7)+(1*7)=143
143 % 10 = 3
So 1093430-77-3 is a valid CAS Registry Number.

supporting information; experimental part, p. 49 - 52 (2009/07/04)
A formal synthesis of (±)-roseophilin is described. Scandium(lll)-catalyzed Nazarov cyclization of 2,5-disubstituted N-tosylpyrrole 19 gives a 5,5'-fused ketopyrrole, and ansa-bridge formation via π-allyl palladium macrocyclization gives 21.
