427898-75-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 427898-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,7,8,9 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 427898-75:
(8*4)+(7*2)+(6*7)+(5*8)+(4*9)+(3*8)+(2*7)+(1*5)=207
207 % 10 = 7
So 427898-75-7 is a valid CAS Registry Number.

Synthesis of nonenolizing 2-acylcyclohex-2-enones
Oliveira-Ferrer, Leticia,Schmidt, Kerstin,Margaretha, Paul
, p. 3818 - 3821 (2007/10/03)
Cyclohexanones 2b and 2c represent the first examples of nonenolizing 2-acylcyclohex-2-enones, as they bear H-atoms neither at C(4) or C(6) of the enone ring, nor at the C-atom vicinal to the exocyclic carbonyl group. While the CF3CO group in 2
