Check Digit Verification of cas no

The CAS Registry Mumber 75187-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,1,8 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75187-47:
(7*7)+(6*5)+(5*1)+(4*8)+(3*7)+(2*4)+(1*7)=152
152 % 10 = 2
So 75187-47-2 is a valid CAS Registry Number.

Acylation of aromatic substrates with ketenes. An example of vinyl oxocation reactivity.

Fountain, K.R.,Heinze, Pamela,Sherwood, Mark,Maddex, Dave,Gerhardt, Greg

, p. 1198 - 1205 (2007/10/02)

Acylations of aromatic substrates with ketenes involve the reactivity of species similar to vinyl cations.Resonance stabilization of ketene-aluminum chloride complexes seems to make these complexes less reactive than corresponding vinyl cations.The kinetic isotope effect of the reaction with dimethylketene and benzene is 1.06, compatible with vinylcation cases, but not with acylation with CH3COBF4 types of electrophiles.Substrate specificity was determined from k (toluene)/k (benzene) values.It was 47.2 for dimethylketene and 173.7 for diphenylketene.The diphenylketene-aluminum chloride complex could be isolated.
