Check Digit Verification of cas no

The CAS Registry Mumber 139705-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,0 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139705-14:
(8*1)+(7*3)+(6*9)+(5*7)+(4*0)+(3*5)+(2*1)+(1*4)=139
139 % 10 = 9
So 139705-14-9 is a valid CAS Registry Number.

Monomer and Dimer 1,3-Diaza-2-phosphaallyllithium Complexes: Structures and Ambident Reactivity

Detsch, Ralph,Niecke, Edgar,Nieger, Martin,Schoeller, Wolfgang W.

, p. 1119 - 1124 (2007/10/02)

Metallation of the NH-functional amino(imino)phosphaes Mes*NPNHR (R = CPh3; Ad, tBu) 1a-c yields the 1,3-diaza-2-phosphaallyllithium compounds 2a-c.The crystal structure shows an ether-stabilized monomer of 2a and a solvent-free dimer with an eight-membered ring in the case of 2b, c.The reaction of 2b with chlorodiphenylphosphane yields, dependent on the reaction conditions, (phosphanylamino)iminophosphane 3 or bis(imino)phosphanylphosphorane 4.The structural and reactivity is discussed on the basis of ab initio calculations.Key Words: 1,3-Diaza-2-phosphaallyllithium / Calculations, ab initio
