Check Digit Verification of cas no

The CAS Registry Mumber 64633-00-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,3 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64633-00:
(7*6)+(6*4)+(5*6)+(4*3)+(3*3)+(2*0)+(1*0)=117
117 % 10 = 7
So 64633-00-7 is a valid CAS Registry Number.

COMPLEX FORMATION OF D- AND F-ELEMENTS WITH SULPHUR ORGANIC COMPOUNDS IN EXTRAKTION EQUILIBRIA

Murinov, Yu. I.

, p. 65 - 110 (2007/10/02)

The regularities in reactivities of some mono- and polydentate organosulphur compounds have been established for complex formation with metal salts in extraction-sorption equilibria.Their reactivities have been shown to depend upon the spatial arrangement of donor centres in an extractant.New classes of polydentate extractants (keto sulphides, amino-sulphides, keto-aminosulphides) have been suggested. Chemical properties of coordinative extractions and sorptions have been investigated for d- and f-elements to be the most intrinsic for the above mentioned class.The keto group has been found to affect the electron density of sulphur in the keto sulphides, thus preventing undesirable redox reactions between an extractant and the isolated metal ion.The coordination character and properties of extracted and sorbated complexes of d- and f-elements with organosulphur compounds have been determined. The donor centres of polydentate organosulphur ligands in the process of complex formation with d- and f-elements have been detected by IR-, ESR-, PMR-, and Raman spectral analyses.
