Check Digit Verification of cas no
The CAS Registry Mumber 146918-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,9,1 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 146918-57:
(8*1)+(7*4)+(6*6)+(5*9)+(4*1)+(3*8)+(2*5)+(1*7)=162
162 % 10 = 2
So 146918-57-2 is a valid CAS Registry Number.

On the Oximation of Diaryl-β-diketones
Bandiera, T.,Gruenanger, P.,Albini, F. Marinone
, p. 1423 - 1428 (2007/10/02)
The reaction of asymmetrically substituted β-diketones with hydroxylamine to give 3,5-diarylisoxazoles has been re-investigated, and has been found to occur with a low degree of site-selectivity unless steric effects are operating.The isoxazole that has t
