Check Digit Verification of cas no

The CAS Registry Mumber 891-87-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,9 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 891-87:
(5*8)+(4*9)+(3*1)+(2*8)+(1*7)=102
102 % 10 = 2
So 891-87-2 is a valid CAS Registry Number.

Some new polyfluorinated 1,3,4-oxadiazoles have been obtained via a two-step method.The cycloadditions of the 1,3,4-oxadiazoles have been studied and an analysis of the energies of the frontier orbitals calculated by the MNDO method indicates a LUMO-dependent pathway for cycloaddition.

John, Earnest Obed,Kirchmeier, Robert L.,Shreeve, Jean'ne M.

, p. 333 - 343 (2007/10/02)

Oxalyl chloride was reacted with sodium-5-(difluoroamino)-difluoromethyltetrazolate or sodium-5-pentafluoroethyltetrazolate to form f = NF2CF2 (7)>, and with F2NCF2C(NH2)=NOH to give 2 (5) which may be dehydrated to the 1,2,4-oxadiazole (6).Both sodium salts can be reacted with perfluoroacyl acid chlorides to form 2,5-disubstituted 1,3,4-oxadiazoles, where Rf'=NF2CF2 and Rf = CF3 (8), C2F5 (9) or C3F7 (10); Rf'= C2F5 and Rf = CF3 (11) or C2F5 (12).
