2785-85-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2785-85-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2785-85:
(6*2)+(5*7)+(4*8)+(3*5)+(2*8)+(1*5)=115
115 % 10 = 5
So 2785-85-5 is a valid CAS Registry Number.

Tobacco smoke chemistry. 2. Alkyl and alkenyl substituted guaiacols found in cigarette smoke condensate.

Arnarp,Bielawski,Dahlin,Dahlman,Enzell,Pettersson

, p. 44 - 50 (2007/10/02)

A series of alkyl and alkenyl substituted guaiacols, which comprise a group of biologically and organoleptically active compounds, have been synthesized. Mass spectra and GC retention times for these have been recorded and compared with those obtained for constituents of a weakly acidic fraction of smoke condensate derived from American blend type cigarettes. On the basis of these results, 25 guaiacols have been identified, 18 of which have not been detected in tobacco smoke condensate previously.
