Check Digit Verification of cas no
The CAS Registry Mumber 73442-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,4 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73442-46:
(7*7)+(6*3)+(5*4)+(4*4)+(3*2)+(2*4)+(1*6)=123
123 % 10 = 3
So 73442-46-3 is a valid CAS Registry Number.

Eicher, Theophil,Urban, Manfred
, p. 408 - 423 (2007/10/02)
The reaction of diphenylcyclopropenone (1a) and other diarylcyclopropenones (1b-e) with ynamines leads to the violet 3-aminocyclopentadienones 8, 24, 28, in some cases to the blue 2-aminocyclopentadienones 35 as by-products.The structure of these compound
