123294-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123294-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,9 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123294-20:
(8*1)+(7*2)+(6*3)+(5*2)+(4*9)+(3*4)+(2*2)+(1*0)=102
102 % 10 = 2
So 123294-20-2 is a valid CAS Registry Number.

SN2 ADDITIONS OF CUPRATES TO SULFONE AND ESTER-POLARIZED CYCLOPENTENYLIC SYSTEMS
Pan, Y.,Hutchinson, D. K.,Nantz, M. H.,Fuchs, P. L.
, p. 467 - 478 (2007/10/02)
The stereochemistry of SN2' addition of cuprates to sulfone and ester-polarized cyclopentenyl systems is shown to depend upon the nature of the leaving group.Allyl ammonium salts usually undergo stereospecific synfacial addition reactions.
