Check Digit Verification of cas no

The CAS Registry Mumber 74077-06-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,7 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74077-06:
(7*7)+(6*4)+(5*0)+(4*7)+(3*7)+(2*0)+(1*6)=128
128 % 10 = 8
So 74077-06-8 is a valid CAS Registry Number.

Oxidation of Alkenes by Iodine Tris(trifluoroacetate). On the cis-Effect of the Trifluoroacetate Group in Oxidations

Buddrus, Joachim,Plettenberg, Horst

, p. 1494 - 1506 (2007/10/02)

Iodine tris(trifluoroacetate) oxidizes alkenes to α-glycol bis(trifluoroacetates) (eq. (1) and tab. 1).By-products are acylals emerging out of a 1,2-shift (eq. (3)). 1,2-Disubstituted alkenes are mainly transformed into cis-glycol derivatives and tri- and tetrasubstituted alkenes to cis/trans mixtures.The oxidations proceed via 2-acyloxy-1,3-dioxolanes, formerly postulated by Winstein et al. as intermediates in similar oxidations, but only now isolated (comp. 3) and examined by NMR and rearranged to the corresponding α-glycols (3 -> 5).A similar reaction course isproposed for certain other alkene oxidations known from literature, in which a trifluoroacetate group is involved and which proceed under cis-addition (table 3).
