Check Digit Verification of cas no

The CAS Registry Mumber 263716-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,7,1 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 263716-67:
(8*2)+(7*6)+(6*3)+(5*7)+(4*1)+(3*6)+(2*6)+(1*7)=152
152 % 10 = 2
So 263716-67-2 is a valid CAS Registry Number.

Multistep synthesis of thiazoloquinazolines under microwave irradiation in solution

Besson, Thierry,Guillard, Jér?me,Rees, Charles W.

, p. 1027 - 1030 (2007/10/03)

Thiazolo[5,4-f]quinazolines are synthesised in six or seven steps from 2-amino-5-nitrobenzonitrile. Both heterocyclic rings are fused onto the central benzene ring via imino-1,2,3-dithiazoles which are readily obtained from primary aromatic amines and 4,5-dichloro-1,2,3-dithiazolium chloride (Appel salt). Four of the steps were improved in yield or reaction time or both, compared to conventional heating, by microwave irradiation of solutions of the reactants in a focused open microwave oven.
