Check Digit Verification of cas no
The CAS Registry Mumber 261350-46-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,3,5 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 261350-46:
(8*2)+(7*6)+(6*1)+(5*3)+(4*5)+(3*0)+(2*4)+(1*6)=113
113 % 10 = 3
So 261350-46-3 is a valid CAS Registry Number.

The one-pot synthesis of ten 5-carboxyisoxazoles from the cyclocondensation of β-alkoxyvinyl trichloromethyl ketones [CCl3C(O)C(R2)=C(R1)OR, where R1, R2=H, Me and R=Me, Et] and 2- trichloroacetyl cyclohexanone with hydroxylamine is reported. This work shows that the trichloromethyl group attached to β-alkoxyvinyl trichloromethyl ketones (a heterocyclic CCC building block) is an excellent carboxyl group precursor.
