66428-69-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66428-69-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,2 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 66428-69:
(7*6)+(6*6)+(5*4)+(4*2)+(3*8)+(2*6)+(1*9)=151
151 % 10 = 1
So 66428-69-1 is a valid CAS Registry Number.

Syntheses of the marine metabolites verongamine, hemibastadin-2, and aerothionin using the cyano ylide coupling methodology

Wasserman, Harry H.,Wang, Jianji

, p. 5581 - 5586 (1998)

Syntheses of the marine metabolites verongamine, hemibastadin-2, and aerothionin have been accomplished by a methodology involving the conversion of a carboxylic acid to an acyl cyano phosphorane which may be oxidized to an α,β-diketo nitrile. This strong

Synthesis and structural revision of calafianin, a member of the spiroisoxazole family isolated from the marine sponge, Aplysina gerardogreeni

Ogamino, Takahisa,Nishiyama, Shigeru

, p. 1083 - 1086 (2007/10/03)

Calafianin 1 was successfully synthesized by employing a spiroisoxazoline compound, which was produced by electrochemical oxidation of the oximino-phenol derivative 7 followed by reduction. This investigation revealed a structural revision of 1, the trans

TOTAL SYNTHESES OF (+/-)-AEROTHIONIN AND (+/-)-HOMOAEROTHIONIN

Nishiyama, Shigeru,Yamamura, Shosuke

, p. 3351 - 3352 (2007/10/02)

Both aerothionin and homoaerothionin, the novel metabolites of the sponges Aplysina aerophoba, A. fistularis and Verongia thiona, have been synthesized in racemic form.
