Check Digit Verification of cas no

The CAS Registry Mumber 67173-62-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,7 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67173-62:
(7*6)+(6*7)+(5*1)+(4*7)+(3*3)+(2*6)+(1*2)=140
140 % 10 = 0
So 67173-62-0 is a valid CAS Registry Number.

Nucleophilic substitution in dibenz[b,d]iodolium and 11,12-dihydro-10H-dibenz[b,g]iodocinium cations

Vanchikov,Bobyleva,Komissarova,Kulikov,Tolstaya

, p. 371 - 377 (2007/10/03)

Treatment of dibenz[b,d]iodolium tetrafluoroborate with NO2-, Br-, and N3- ions gave, along with nucleophilic substitution products, 2-nitro-, 2-bromo-, and 2-azido-2′-iodiphenyls, diphenyl, 2-iododiphenyl, and 2,2′-diiododiphenyl (products of one electron reduction), whereas 11,12-dihydro-10H-dibenz[b,g]-iododnium tetrafluoroborate underwent nucleophilic substitution with all three nucleophiles to give a single product in each case: 1-(2-nitrophenyl)-, 1-(2-bromophenyl)-, or 1-(2-azidophenyl)-3-(2-iodophenyl)propane. 1998 Plenum Publishing Corporation.
