73661-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73661-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,6 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73661-97:
(7*7)+(6*3)+(5*6)+(4*6)+(3*1)+(2*9)+(1*7)=149
149 % 10 = 9
So 73661-97-9 is a valid CAS Registry Number.

On the Reaction of Triafulvenes with Ynamines
Eichler, Theophil,Pfister, Theodor,Urban, Manfred
, p. 424 - 450 (2007/10/02)
The reaction of triafulvenes 9 - 11 with ynamines 3 leads to 2-aminofulvenes (12, 20, 28, 31), which are characterized by their spectral data, the hydrolysis giving 4-methylene-2-cyclopenten-1-ones (15, 22, 30, 33) and 4-cyclopenten-1,3-diones (14) and by
