188938-28-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188938-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,3 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188938-28:
(8*1)+(7*8)+(6*8)+(5*9)+(4*3)+(3*8)+(2*2)+(1*8)=205
205 % 10 = 5
So 188938-28-5 is a valid CAS Registry Number.

Total synthesis of bafilomycin A1

Toshima,Jyojima,Yamaguchi,Noguchi,Yoshida,Murase,Nakata,Matsumura

, p. 3271 - 3284 (2007/10/03)

The highly stereoselective total synthesis of the macrolide antibiotic, bafilomycin A1 (1), the first specific potent inhibitor of vacuolar H+-ATPase, has been achieved by a convergent route involving the synthesis and coupling of its 16-membered tetraenic lactone and β-hydroxyl hemiacetal side-chain subunits. The C1-C17 16-membered lactone aldehyde 2 was synthesized through the coupling of the C5-C11 vinyl iodide 4 and the C12-C17 vinylstannane 5, followed by construction of the C1-C4 diene and macrolactonization. The aldol coupling of 2 and the C18-C25 ethyl ketone 3 followed by desilylation provided 1, which was identical with natural bafilomycin A1. The key synthetic segments 3-5 were effectively synthesized from the readily available chiral materials, D-glucose, ethyl (S)-lactate, and methyl (S)-3-hydroxy-2-methylpropionate, respectively.
