Check Digit Verification of cas no

The CAS Registry Mumber 519156-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,9,1,5 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 519156-98:
(8*5)+(7*1)+(6*9)+(5*1)+(4*5)+(3*6)+(2*9)+(1*8)=170
170 % 10 = 0
So 519156-98-0 is a valid CAS Registry Number.

Regioselective synthesis of cis- and trans-2,4,5-triarylimidazolines and 2,4,5-triarylimidazoles from available reagents

Lozinskaya,Tsybezova,Proskurnina,Zefirov

, p. 674 - 678 (2007/10/03)

Novel data were obtained concerning the reaction of aromatic aldehydes with ammonia. A preparative method for the synthesis of new substituted 1,3,5-triaryl-2,4-diazapenta-1,4-dienes was developed. These products are the starting reactants for syntheses of cis- and trans-2,4,5-triaryl-2-imidazolines and 2,4,5-triarylimidazoles.
