Check Digit Verification of cas no

The CAS Registry Mumber 1087041-15-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,7,0,4 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1087041-15:
(9*1)+(8*0)+(7*8)+(6*7)+(5*0)+(4*4)+(3*1)+(2*1)+(1*5)=133
133 % 10 = 3
So 1087041-15-3 is a valid CAS Registry Number.

Sequential organocatalyzed michael addition/[3 + 2]-heterocyclization for the stereoselective synthesis of fused-isoxazoline precursors of enantiopure cyclopentanoids

Bonne, Damien,Salat, Lydie,Dulcere, Jean-Pierre,Rodriguez, Jean

supporting information; experimental part, p. 5409 - 5412 (2009/06/28)

(Chemical Equation Presented) We propose an asymmetric synthesis of functionalized cyclopentanoids bearing up to four stereogenic centers from easily accessible nitroalkenes and unsaturated aldehydes. The overall sequence includes an enantioselective organocatalytic Michael addition and a [3 + 2]-heterocyclization between an in situ generated silylnitronate and the unactivated double bond. Finally, the fused isoxazoline can be further transformed to various cyclopentanoids.
