498554-12-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 498554-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,8,5,5 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 498554-12:
(8*4)+(7*9)+(6*8)+(5*5)+(4*5)+(3*4)+(2*1)+(1*2)=204
204 % 10 = 4
So 498554-12-4 is a valid CAS Registry Number.

Synthesis of the ABCDEF-ring of ciguatoxin 3C

Sato, Takuto,Nogoshi, Keisuke,Goto, Akiyoshi,Domon, Daisuke,Kawamura, Natsumi,Nomura, Yoshitaka,Sato, Daisuke,Tanaka, Hideki,Murai, Akio,Katoono, Ryo,Kawai, Hidetoshi,Suzuki, Takanori,Fujiwara, Kenshu,Kondo, Yoshihiko,Akiba, Uichi

, p. 703 - 726 (2017/01/16)

The synthesis of the ABCDEF-ring of ciguatoxin 3C was achieved via a route that included anion coupling of a dimethyldithioacetal mono-S-oxide derivative corresponding to the AB-ring and an aldehyde corresponding to the EF-ring, followed by cyclization us

Convergent synthesis of the ABCDE-ring part of ciguatoxin CTX3C

Fujiwara, Kenshu,Goto, Akiyoshi,Sato, Daisuke,Ohtaniuchi, Yuko,Tanaka, Hideki,Murai, Akio,Kawai, Hidetoshi,Suzuki, Takanori

, p. 7011 - 7014 (2007/10/03)

The ABCDE-ring part (2) of ciguatoxin CTX3C was concisely synthesized from the AB-ring and the E-ring parts (4 and 5).

Synthesis of the AB-ring segment for the convergent construction of the left half in ciguatoxin

Tanaka, Hideki,Kawai, Kentaro,Fujiwara, Kenshu,Murai, Akio

, p. 10017 - 10031 (2007/10/03)

The synthesis of the AB-ring segment aiming at the convergent construction of the left half in ciguatoxin (CTX1B) has been achieved by a strategy based on ring-closing metathesis (RCM) and diastereocontrolled hydroboration to cyclic vinyl ethers.
