Check Digit Verification of cas no

The CAS Registry Mumber 1309459-30-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,4,5 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1309459-30:
(9*1)+(8*3)+(7*0)+(6*9)+(5*4)+(4*5)+(3*9)+(2*3)+(1*0)=160
160 % 10 = 0
So 1309459-30-0 is a valid CAS Registry Number.

Efficient multi-component synthesis of highly substituted imidazoles utilizing P2O5/SiO2 as a reusable catalyst

Shaterian, Hamid Reza,Ranjbar, Mohammad,Azizi, Kobra

experimental part, p. 1635 - 1645 (2012/01/06)

Phosphorus pentoxide supported on silica gel (P2O 5/SiO2) has been used as an efficient and reusable catalyst for the one-pot pseudo four-component synthesis of 2,4,5-trisubstituted imidazoles from benzil or benzoin, aldehydes, and ammonium acetate. It was also used for four-component preparation of 1,2,4,5-tetrasubstituted imidazoles from benzil or benzoin, aldehydes, primary amine, and ammonium acetate under thermal solvent-free conditions. The remarkable features of this new procedure are high conversions, cleaner reaction, simple experimental and work-up procedures and also the catalyst can be easily separated from the reaction mixture and reused several times without any loss of its activity.
