1452139-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1452139-37-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,2,1,3 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1452139-37:
(9*1)+(8*4)+(7*5)+(6*2)+(5*1)+(4*3)+(3*9)+(2*3)+(1*7)=145
145 % 10 = 5
So 1452139-37-5 is a valid CAS Registry Number.

Palladium catalyzed cyclizations of oxime esters with 1,2-disubstituted alkenes: Synthesis of dihydropyrroles
Race, Nicholas J.,Bower, John F.
supporting information, p. 4616 - 4619 (2013/09/24)
Pd-catalyzed cyclizations of oxime esters with 1,2-dialkylated alkenes provide an entry to chiral dihydropyrroles. Substrate and catalyst controlled strategies for selective product formation (vs alternative pyrroles) are outlined.
