152495-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152495-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,4,9 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 152495-65:
(8*1)+(7*5)+(6*2)+(5*4)+(4*9)+(3*5)+(2*6)+(1*5)=143
143 % 10 = 3
So 152495-65-3 is a valid CAS Registry Number.

Synthesis of racemic and optically active cispentacin (FR109615) using intramolecular nitrone-olefin cycloaddition
Konosu,Oida
, p. 1012 - 1018 (1993)
Synthesis of racemic and optically active cispentacin ((-)-1) is described. Intramolecular nitrone-olefin cycloaddition of the alkenyl nitrone 7 gave cis-isoxazolidine (±)-8, which was transformed into (±)-1 by sequential reactions involving catalytic hyd
