89241-22-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89241-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89241-22:
(7*8)+(6*9)+(5*2)+(4*4)+(3*1)+(2*2)+(1*2)=145
145 % 10 = 5
So 89241-22-5 is a valid CAS Registry Number.

THE PHOTOCHEMICAL OR THERMAL REARRANGEMENT OF OXAZIRANES AS A METHOD IN ALKALOID SYNTHESIS
Kuehne, Martin E.,Parsons, W. H.
, p. 3763 - 3766 (2007/10/02)
The conversion of cyclic ketones to β-arylethyl amine derived imines, their oxidation to oxaziranes and subsequent photochemical rearrangement to N-(β-arylethyl) lactams was probed as a potential method for alkaloid syntheses.
