Check Digit Verification of cas no
The CAS Registry Mumber 932-55-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 932-55:
(5*9)+(4*3)+(3*2)+(2*5)+(1*5)=78
78 % 10 = 8
So 932-55-8 is a valid CAS Registry Number.

Electrophilic catalysis in nucleophilic substitution reactions in ionic liquids

2-Chlorotropone was obtained from 2-tosyloxytropone in 88% yield in the recyclable ionic medium BMIMBF4/LiCl. That Li+ acts as a Lewis acid was proven by the lack of reactivity of 2-tosyloxytropone, under the above conditions, on replacing LiCl with NaCl or BMIMCl, or using BMIMCl alone, or a BMIMBF4/MeCN/KCl mixture. 2-Bromo- and 2-iodotropone were obtained along similar lines from LiBr or LiI, respectively, whereas LiF proved unreactive.

Readily accessible 10-tosyloxycolchicide (1) and LiX (X=Cl or Br or I) in MeOH/BF3·Et2O at reflux give 10-chloro- (2), 10-bromo- (4), or 10-iodocolchicide (5), in good yields. 9-Chloro- (7) and 9-bromoisocolchidide (8) can be similarly obtained from 9-tosyloxyisocolchidide (6) and the method applies also to troponoids.
