33644-59-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33644-59-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,4 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33644-59:
(7*3)+(6*3)+(5*6)+(4*4)+(3*4)+(2*5)+(1*9)=116
116 % 10 = 6
So 33644-59-6 is a valid CAS Registry Number.

Intramolecular trapping of the quinone methide from reductive cleavage of daunomycin with oxygen and nitrogen nucleophiles
Gaudiano, Giorgio,Frigerio, Massimo,Bravo, Pierfrancesco,Koch, Tad H.
, p. 6704 - 6709 (2007/10/02)
Intramolecular trapping with oxygen and nitrogen nucleophilic sites of the quinone methide from reductive cleavage of daunomycin (1a) is described. The oxygen and nitrogen nucleophilic sites were located at the 13-position of daunomycin in oxime, semicarb
