Check Digit Verification of cas no

The CAS Registry Mumber 799768-50-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,9,7,6 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 799768-50:
(8*7)+(7*9)+(6*9)+(5*7)+(4*6)+(3*8)+(2*5)+(1*0)=266
266 % 10 = 6
So 799768-50-6 is a valid CAS Registry Number.

Electronic effects in olefin oxidation by imidoosmium(VIII) compounds

Muniz, Kilian

, p. 2243 - 2252 (2004)

Imido osmium(VIII) complexes are versatile oxidants for C-C double bond functionalisation. Despite their structural similarity with OsO4 their reactivity cannot always be compared with this seminal reagent. Detailed investigations including kinetic competition experiments are presented that uncover the electronic and steric preferences of osmium imido complexes. The different behaviour of OsO4 and its imido derivatives towards tertiary amines and diamines is clarified. Hammett correlation studies reveal that the reactivity spectrum of the respective oxidants ranges from a strongly electrophilic behaviour in the case of OsO4 to a rather nucleophilic character as encountered for OsO(NtBu)3.
