Check Digit Verification of cas no
The CAS Registry Mumber 68077-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,7 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68077-28:
(7*6)+(6*8)+(5*0)+(4*7)+(3*7)+(2*2)+(1*8)=151
151 % 10 = 1
So 68077-28-1 is a valid CAS Registry Number.

Improved synthesis of trifluoromethyl sulfones used as intermediates for the preparation of di- or tri-substituted olefins
Eugene, Fabrice,Langlois, Bernard,Laurent, Eliane
, p. 301 - 310 (2007/10/02)
Primary and secondary trifluoromethyl sulfones (triflones) are efficiently obtained from easily available sodium trifluoromethanesulfinate (triflinate) and alkyl bromides in N,N-dimethylacetamide.This technique is more powerful than the potassium triflinate/acetonitrile system.Ethyl aconitate can be also produced in one step from ethyl bromoacetate and diisopropylethylamine, sodium triflinate being a catalyst.
