269409-64-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 269409-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,4,0 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 269409-64:
(8*2)+(7*6)+(6*9)+(5*4)+(4*0)+(3*9)+(2*6)+(1*4)=175
175 % 10 = 5
So 269409-64-5 is a valid CAS Registry Number.

Recent advances in the synthesis of pamamycin-607

Metz, Peter,Bernsmann, Heiko

, p. 383 - 384 (1999)

Using sultones as crucial intermediates, a short and highly stereoselective synthesis of a precursor of the larger fragment and the methyl ester of the smaller fragment of the macrodiolide pamamycin-607 was achieved.

Toward the synthesis of pamamycin-607
