Check Digit Verification of cas no
The CAS Registry Mumber 121198-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121198-91:
(8*1)+(7*2)+(6*1)+(5*1)+(4*9)+(3*8)+(2*9)+(1*1)=112
112 % 10 = 2
So 121198-91-2 is a valid CAS Registry Number.

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.
