Check Digit Verification of cas no

The CAS Registry Mumber 17637-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,3 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17637-66:
(7*1)+(6*7)+(5*6)+(4*3)+(3*7)+(2*6)+(1*6)=130
130 % 10 = 0
So 17637-66-0 is a valid CAS Registry Number.

Mass-spectrometric study on ion-molecule reactions of CH5+, C2H5+, and C3H5+ with C9-C19 alkylbenzenes in an ion trap

Tanaka, Yuki,Tsuji, Masaharu

, p. 241 - 252 (2002)

Chemical ionization of alkylbenzenes (PhCxH2x + 1 = M: x = 3-13) by the CH5+, C2H5+, and C3H5+ ions has been studied under a reactant-ion selective mode of an ion-trap type of GC/MS. The dominant product ions for short-chain reagents (x +, [Phil + H]+, and CxH2x + 1+ ions, produced through proton-transfer to benzene ring. On the other hand, the dominant product ions for long-chain reagents (x ≥ 7) were CyH2y + 1+ (y yH2y+ (y ≤ x) ions. The former ions are produced through the attack of the reactant ions on the alkyl chain and/or the benzene ring, while the latter ones are exclusively formed through the attack of the reactant ions on the alkyl chain. Major formation processes of CyH2y + 1+ and PhCyH2y+ ions in each reaction were discussed on the basis of observed distributions and calculated thermochemical data.
