476687-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 476687-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,6,6,8 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 476687-99:
(8*4)+(7*7)+(6*6)+(5*6)+(4*8)+(3*7)+(2*9)+(1*9)=227
227 % 10 = 7
So 476687-99-7 is a valid CAS Registry Number.

Convergent Synthesis of the ABCDEF-Ring System of Yessotoxin and Adriatoxin
Suzuki, Keisuke,Nakata, Tadashi
, p. 3943 - 3946 (2007/10/03)
(Matrix Presented) The convergent synthesis of the ABCDEF-ring system of yessotoxin and adriatoxin was accomplished. This efficient convergent strategy was performed on the basis of the coupling of the acetylide of the A-ring and the triflate of the DEF-r
