Check Digit Verification of cas no

The CAS Registry Mumber 1339941-27-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,9,9,4 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1339941-27:
(9*1)+(8*3)+(7*3)+(6*9)+(5*9)+(4*4)+(3*1)+(2*2)+(1*7)=183
183 % 10 = 3
So 1339941-27-3 is a valid CAS Registry Number.

First examples of spirooxaphosphirane complexes

Perez, Janaina Marinas,Klein, Melina,Kyri, Andreas Wolfgang,Schnakenburg, Gregor,Streubel, Rainer

, p. 5636 - 5640 (2011)

The reaction of a transient Li/Cl phosphinidenoid pentacarbonyltungsten complex (R = CH(SiMe3)2) with cyclohexanone, cyclopentanone, and cyclobutanone yielded the novel, atropisomeric spirooxaphosphirane complexes 3a,b-5a,b, while 2,3-diphenylcyclopropenone furnished selectively the 1,2-dihydrophosphet- 2-one complex 6. All complexes have been characterized by heteronuclear NMR, mass spectrometry, and singlecrystal X-ray analysis in the case of 4a, 5a, and 6.
