570402-54-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 570402-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,0,4,0 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 570402-54:
(8*5)+(7*7)+(6*0)+(5*4)+(4*0)+(3*2)+(2*5)+(1*4)=129
129 % 10 = 9
So 570402-54-9 is a valid CAS Registry Number.

The first total synthesis of lamellarin α 20-sulfate, a selective inhibitor of HIV-1 integrase

Yamaguchi, Tomohiro,Fukuda, Tsutomu,Ishibashi, Fumito,Iwao, Masatomo

, p. 3755 - 3757 (2006)

The first total synthesis of lamellarin α 20-sulfate (1), a selective inhibitor of HIV-1 integrase, has been completed. The lamellarin α core in which 13-OH and 20-OH were differentially protected by isopropyl and benzyl groups, respectively, was construc

Short and flexible route to 3,4-diarylpyrrole marine alkaloids: Syntheses of permethyl storniamide A, ningalin B, and lamellarin G trimethyl ether

Iwao, Masatomo,Takeuchi, Toshiro,Fujikawa, Naotaka,Fukuda, Tsutomu,Ishibashi, Fumito

, p. 4443 - 4446 (2007/10/03)

A highly efficient route to 3,4-diarylpyrrole marine alkaloids has been developed using Hinsberg-type pyrrole synthesis and palladium-catalyzed Suzuki cross-coupling of the 3,4-dihydroxypyrrole bis-triflate derivatives as key reactions. Based on this approach, formal syntheses of permethyl storniamide A and ningalin B, and a total synthesis of lamellarin G trimethyl ether have been achieved.
