Check Digit Verification of cas no

The CAS Registry Mumber 103149-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,1,4 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103149-58:
(8*1)+(7*0)+(6*3)+(5*1)+(4*4)+(3*9)+(2*5)+(1*8)=92
92 % 10 = 2
So 103149-58-2 is a valid CAS Registry Number.

NEW RESULTS OF REACTIONS WITH HEXAFLUOROACETONE AND RELATED COMPOUNDS

Roesky, Herbert W.

, p. 123 - 140 (1985)

The reaction of hexafluoroacetone (HFA) with CN- and SCN-compounds of main group and transition elements is described.The cyclic addition reactions to the CN-moiety is catalyzed by base, preferentially triethylamine.Of particular interest are the adducts of HFA with (SCN)2 and Hg(SCN)2.They are precursors for various new compounds containing six-membered rings.The elimination of oxygen by the rection of HFA with N=WCl3 may be considered as a new Wittig type reaction.The dimer of hexafluorothioacetone inserts into its S-C bond the carbon atom of an isonitrile group to yield five-membered rings.PCl5 adds to (CF3)2C=C(CN)2, prepared from HFA and CH2(CN)2, to form a six-membered phosphorus containing ring.
