92250-34-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92250-34-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,2,5 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 92250-34:
(7*9)+(6*2)+(5*2)+(4*5)+(3*0)+(2*3)+(1*4)=115
115 % 10 = 5
So 92250-34-5 is a valid CAS Registry Number.

Photomediated asymmetric synthesis of (-)-cuparene.
Grainger, Richard S,Patel, Aslam
, p. 1072 - 1073 (2007/10/03)
Generation of a benzylic quaternary stereocentre via the photomediated cyclisation of a chiral alpha-(aminobutyl)styrene followed by a microwave-assisted Cope elimination has led to a total synthesis of the sesquiterpene (-)-cuparene.
