438002-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 438002-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,0,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 438002-76:
(8*4)+(7*3)+(6*8)+(5*0)+(4*0)+(3*2)+(2*7)+(1*6)=127
127 % 10 = 7
So 438002-76-7 is a valid CAS Registry Number.

Synthesis of the FGH ring fragment of ciguatoxin
Sasaki,Noguchi,Tachibana
, p. 1337 - 1340 (2007/10/03)
Stereoselective synthesis of the FGH ring fragment of ciguatoxin is described. The key steps in the present synthesis are an intramolecular radical cyclization to construct oxepane ring G and ring-closing metathesis reaction to construct hexahydrooxonin ring F.
