Check Digit Verification of cas no

The CAS Registry Mumber 94052-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,0,5 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94052-40:
(7*9)+(6*4)+(5*0)+(4*5)+(3*2)+(2*4)+(1*0)=121
121 % 10 = 1
So 94052-40-1 is a valid CAS Registry Number.

One-pot synthesis of 2,5-disubstituted pyrimidines from nitriles

Frutos, Rogelio P.,Wei, Xudong,Patel, Nitinchandra D.,Tampone, Thomas G.,Mulder, Jason A.,Busacca, Carl A.,Senanayake, Chris H.

, p. 5800 - 5803 (2013/07/25)

A practical, one-step process for the synthesis of 2,5-disubstituted pyrimidines is presented. The protocol proved to be general for the synthesis of a variety of pyrimidine-containing compounds bearing an assortment of functional groups.

A facile and versatile route to 2-substituted-4(3H)-quinazolinones and quinazolines

Connolly,Guiry

, p. 1707 - 1710 (2007/10/03)

A range of 2-aryl and 2-alkyl quinazolinones have been prepared in moderate to good yields from the reaction of anthranilic acid and the appropriately substituted imidate in a facile, mild, onepot procedure. Subsequent reaction with phosphorus oxychloride afforded the corresponding 4-chloro-2-substituted quinazolines, which are useful synthetic intermediates, in good to high yields. Product isolation was facilitated by the development of work up procedures for both reactions that did not include purification by column chromatography.
