Check Digit Verification of cas no

The CAS Registry Mumber 182866-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,8,6 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 182866-73:
(8*1)+(7*8)+(6*2)+(5*8)+(4*6)+(3*6)+(2*7)+(1*3)=175
175 % 10 = 5
So 182866-73-5 is a valid CAS Registry Number.

Rapid synthesis of oxazoles under microwave conditions

Brain, Christopher T.,Paul, Jane M.

, p. 1642 - 1644 (1999)

A new and efficient variation of the Robinson-Gabriel oxazole synthesis is described. Oxazoles were prepared by cyclodehydration of 2-acylamino carbonyl compounds with Burgess reagent under monomode microwave irradiation.

Studies towards the synthesis of diazonamide A. Synthesis of the indole bis-oxazole fragment

Bagley,Hind,Moody

, p. 6897 - 6900 (2007/10/03)

The indole bis-oxazole 2, a potential intermediate for the synthesis of the marine natural product diazonamide A 1, has been synthesised, and attempts to construct the model macrocycle (ring B) 3 are also described; in both approaches rhodium carbenoid N-H insertion reactions are used in key steps.
