Check Digit Verification of cas no

The CAS Registry Mumber 106865-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,8,6 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106865-59:
(8*1)+(7*0)+(6*6)+(5*8)+(4*6)+(3*5)+(2*5)+(1*9)=142
142 % 10 = 2
So 106865-59-2 is a valid CAS Registry Number.

Synthesis and characterization of new heterocyclic compounds of tungsten, selenium, and tellurium

Katti, Kattesh V.,Seseke, Ulrich,Roesky, Herbert W.

, p. 814 - 816 (2008/10/08)

The bis-silylated phosphorane Me3SiNP(Ph2)CH2(Ph2)PNSiMe 3 (1) reacts with WF6, WCl6, SeOCl2 and TeCl4 to form new heterocyclic compounds containing tungsten [NP(Ph2)CH2(Ph2)PNWF4 (2), NP(Ph2)CH2(Ph2)PNWCl4 (3)], selenium [NP(Ph2)CH2(Ph2)PNSeCl2 (5)], and tellurium [NP(Ph2)CH2(Ph2)PNTeCl2 (6)], respectively. The reaction of the unsaturated heterocyclic compound 3 with the base DBU leads to the formation of a conjugated heterocyclic compound, NP(Ph2)CH(Ph2)PNWCl3 (4), through the elimination of DBU·HCl. 1H, 31P, 19F, 77Se, and 125Te NMR spectroscopic investigations confirm the structures of compounds 2-6.
