121468-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121468-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,6 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121468-99:
(8*1)+(7*2)+(6*1)+(5*4)+(4*6)+(3*8)+(2*9)+(1*9)=123
123 % 10 = 3
So 121468-99-3 is a valid CAS Registry Number.

Formal synthesis of (-)-α- and (+)-β-Cuparenones, Cuparene, and Laurene
Okano, Kouji,Suemune, Hiroshi,Sakai, Kiyoshi
, p. 1379 - 1385 (2007/10/02)
This paper describes formal synthesis of the title compounds from easily prepared chiral synthon (+)-5.One of the structural features of the cuparene family is the presence of vicinal quaternary carbons on the five-membered ring.The quaternary carbon with
