6931-11-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6931-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,3 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6931-11:
(6*6)+(5*9)+(4*3)+(3*1)+(2*1)+(1*1)=99
99 % 10 = 9
So 6931-11-9 is a valid CAS Registry Number.

Allenyloxime-a new source of heterocyclizations to stable cyclic nitrones

Buchlovi?, Marian,Man, Stanislav,Potá?ek, Milan

experimental part, p. 9953 - 9961 (2009/04/03)

A variety of conditions including reductive and/or basic reagents in aqueous or alcoholic solution was applied to 2,2-dimethylpenta-3,4-dienal oxime. Formation of various five-membered heterocycles with excellent chemical selectivity was observed. Most of the reactions yielded cyclic nitrones with stable dipolar structure and unique functionalities present. All products of cyclization were isolated and fully characterized.
