78657-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78657-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,5 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78657-69:
(7*7)+(6*8)+(5*6)+(4*5)+(3*7)+(2*6)+(1*9)=189
189 % 10 = 9
So 78657-69-9 is a valid CAS Registry Number.

Π-CYCLIZATION: THE SYNTHESIS OF (+/-)-SOLAVETIVONE AND (+/-)-HINESOL
Murai, Akio,Sato, Shingo,Masamune, Tadashi
, p. 1033 - 1036 (2007/10/02)
A general efficient approach leading to the total synthesis of (+/-)-solavetivone, (+/-)-hinesol, and related spirovetivanes, is described.The process involves stereoselective formation of the asymmetric center at C-7 by ?-cyclisation as a key step.
