1415118-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1415118-43-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,5,1,1 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1415118-43:
(9*1)+(8*4)+(7*1)+(6*5)+(5*1)+(4*1)+(3*8)+(2*4)+(1*3)=122
122 % 10 = 2
So 1415118-43-2 is a valid CAS Registry Number.

A chiral pool based approach to antipodes of α-cuparenone
Chavan, Subhash P.,Lasonkar, Pradeep B.
, p. 1496 - 1500,5 (2012/12/12)
A synthetic route to both antipodes of α-cuparenone was achieved from the readily available chiral pool starting material l-malic acid and involved cyclopentannulation as the key step.
