146904-63-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 146904-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,9,0 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 146904-63:
(8*1)+(7*4)+(6*6)+(5*9)+(4*0)+(3*4)+(2*6)+(1*3)=144
144 % 10 = 4
So 146904-63-4 is a valid CAS Registry Number.

Thiono and dithio estes, LII: Reaction of dithiono malonates with N,N-dimethylformamide acetals

Hartke,Kraska

, p. 57 - 60 (2007/10/02)

The reaction of the dithiono malonates 1 with the formamide acetals 2 leads to the 2-dialkylaminomethylene dithionomalonates 4 and the thiono acrylates 6. The condensation of 4 with hydrazines gives rise to the pyrazoles 7 and 8, with hydroxylamine sulfon
