439915-88-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 439915-88-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,9,1 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 439915-88:
(8*4)+(7*3)+(6*9)+(5*9)+(4*1)+(3*5)+(2*8)+(1*8)=195
195 % 10 = 5
So 439915-88-5 is a valid CAS Registry Number.

Asymmetric synthesis of diversely substituted N-hydroxypyrrolidines using cycloadditions with chiral nitrone enolate/ylids
Hanessian, Stephen,Bayrakdarian, Malken
, p. 967 - 971 (2002)
A stereoselective synthesis of diversely substituted N-hydroxypyrrolidines is reported, based on the cycloaddition reaction of chiral non-racemic nitrone ylids with a variety of α,β-unsaturated esters.
