169895-46-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 169895-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,8,9 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 169895-46:
(8*1)+(7*6)+(6*9)+(5*8)+(4*9)+(3*5)+(2*4)+(1*6)=209
209 % 10 = 9
So 169895-46-9 is a valid CAS Registry Number.

Stereocontrolled Total Synthesis of Hemibrevetoxin B

Kadota, Isao,Yamamoto, Yoshinori

, p. 6597 - 6606 (2007/10/03)

The stereocontrolled total synthesis of hemibrevetoxin B (1) has been achieved in 56 steps and 0.75% overall yield from D-mannose. The intramolecular reaction of γ-alkoxyallylstannane with aldehyde is a key step for the present total synthesis. Thus, the BF3·OEt2-mediated reaction of 24 gave 6 as a sole product. We encountered difficulty in the synthesis of γ-alkoxyallylstannane 30 from the corresponding allyl ether 29 in which the γ-alkoxy substituent became sterically quite bulky. This problem was solved by developing the acetal cleavage method for the synthesis of γ-alkoxyallylstannanes. The cyclization of 38 proceeded smoothly to give the key intermediate 5 in a highly stereoselective manner. Construction of the α-vinyl aldehyde and (Z)-diene moieties were performed using Nicolaou's protocol.
