332035-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 332035-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,0,3 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 332035-55:
(8*3)+(7*3)+(6*2)+(5*0)+(4*3)+(3*5)+(2*5)+(1*5)=99
99 % 10 = 9
So 332035-55-9 is a valid CAS Registry Number.

Synthesis of (S)-(-)-β-cuparenone and (S)-(-)-cuparene
Aavula, Bhasker Reddy,Cui, Qi,Mash, Eugene A.
, p. 4681 - 4686 (2007/10/03)
A short and efficient synthesis of the title compounds is described. (S)-(-)-β-Cuparenone was prepared in 31% yield from p-tolualdehyde and mesityl oxide in eight steps. Absolute stereochemistry was established by means of a diastereoselective cyclopropan
