Check Digit Verification of cas no

The CAS Registry Mumber 238742-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,7,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 238742-40:
(8*2)+(7*3)+(6*8)+(5*7)+(4*4)+(3*2)+(2*4)+(1*0)=150
150 % 10 = 0
So 238742-40-0 is a valid CAS Registry Number.

Synthesis and characterization of lithium complexes of 2- (diphenylphosphanylamino)pyridine and N,2-bis(diphenylphosphanyl)benzeneamine

Xavier, Kochappilly O.,Smolensky, Elena,Kapon, Moshe,Aucott, Stephen M.,Woollins, J. Derek,Eisen, Moris S.

, p. 4795 - 4802 (2004)

Lithium complexes of 2-(diphenylphosphinoamino)pyridine and N,2-bis(diphenylphosphanyl)benzeneamine have been synthesized from the corresponding neutral compounds. In the former complex, the metal ion is coordinated to both nitrogen atoms, forming a constrained four-membered ring, whereas the latter complex forms a five-membered ring as the metal ion coordinates preferentially to the phosphorus atom. Coordination of the metal ion in both complexes is dictated primarily by soft-hard interactions and, subsequently, by the constrained geometry of the ring formed. Both lithium complexes and the corresponding neutral compounds have been characterized by single-crystal X-ray diffraction. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
