Check Digit Verification of cas no
The CAS Registry Mumber 57428-56-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,2 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57428-56:
(7*5)+(6*7)+(5*4)+(4*2)+(3*8)+(2*5)+(1*6)=145
145 % 10 = 5

Reaction of FeCl3 with 7-chloro-1-silyloxybicycloheptanes : A way to 2-(1-chloroalkylidene)cyclohexanones.
Blanco, L.,Mansouri, A.
, p. 3239 - 3242 (2007/10/02)
The regioselectivity of the FeCl3-promoted cleavage of the title compounds was studied : 2-(1,1-dichloroalkyl)cyclohexanones were obtained which were converted to 2-(1-chloroalkylidene)cyclohexanones by dehydrochlorination.
