Check Digit Verification of cas no

The CAS Registry Mumber 503839-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,8,3 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 503839-90:
(8*5)+(7*0)+(6*3)+(5*8)+(4*3)+(3*9)+(2*9)+(1*0)=155
155 % 10 = 5
So 503839-90-5 is a valid CAS Registry Number.

One-pot mechanosynthesis of aromatic amides and dipeptides from carboxylic acids and amines

?trukil, Vjekoslav,Bartolec, Boris,Portada, Tomislav,Dilovi?, Ivica,Halasz, Ivan,Margeti?, Davor

, p. 12100 - 12102 (2012)

Environmentally friendly one-pot synthesis of amides, bis-amides and dipeptides by mechanochemical carbodiimide-mediated coupling of carboxylic acids and amines is described; high reaction yields and simple aqueous work-up allow for the clean, practical and fast preparation of a variety of compounds containing the amide bond from readily accessible reagents.
