Check Digit Verification of cas no

The CAS Registry Mumber 15189-06-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,8 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15189-06:
(7*1)+(6*5)+(5*1)+(4*8)+(3*9)+(2*0)+(1*6)=107
107 % 10 = 7
So 15189-06-7 is a valid CAS Registry Number.

Transition metal complexes of a constrained phosphite ester. V. Metal carbonyl complexes of 2,8,9-trioxa-1-phosphaadamantane

Hendricker,McCarley,King, Roy W.,Verkade

, p. 639 - 643 (2008/10/08)

The preparation and characterization of metal carbonyl complexes of 2,8,9-trioxa-1-phosphaadamantane, P(OCH)3(CH2)3, are described. Substitution products obtained from Ni(CO)4 include compounds of the type Ni(CO)4-x[P(OCH)3(CH2)3]x where x = 1, 2, 3, or 4. Synthesis of the mono- and disubstituted complexes of Fe(CO)5, Cr(CO)6, Mo(CO)6, and W(CO)6 with P(OCH)3(CH2)3 is also reported. A study of the carbonyl infrared stretching frequencies implies that P(OCH)3(CH2)3 is equal to other phosphites in π-bonding ability. The proton nmr spectra of the compounds are discussed with special attention given to the disubstituted complexes. The proton nmr spectra of analogous disubstituted complexes of P(OCH2)3CCH3 discussed previously by us (see ref 5) are more rigorously treated.
