Check Digit Verification of cas no

The CAS Registry Mumber 21924-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,2 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21924-94:
(7*2)+(6*1)+(5*9)+(4*2)+(3*4)+(2*9)+(1*4)=107
107 % 10 = 7
So 21924-94-7 is a valid CAS Registry Number.

BF3.SiO2 nanoparticles: A solid phase acidic catalyst for efficient one-pot Hantzsch synthesis of 1,4-dihydropyridines

Sadeghi, Bahareh,Namakkoubi, Ashraf,Hassanabadi, Alireza

, p. 11 - 13 (2013/04/10)

The solvent-free Hantzsch reaction between ethyl acetoacetate or 1,3-indandione, an aromatic aldehyde and ammonium acetate catalysed by BF 3.SiO2 nanoparticles provided an efficient one-step synthesis of 1,4-dihydropyridines in excellent yields.

Synthesis and biological evaluation of novel 1,4-dihydropyridines

Dabholkar, Vijay V.,Patil, Sunil Rajaram,Pandey, Rajesh Vinod

, p. 407 - 408 (2013/09/24)

A series of new, 1,4-dihydropyridines 4 have been synthesized and the structures of the compounds have been confirmed by IR and NMR. Representative compounds were screened for their antimicrobial activity against Gram-negative bacteria, E.coli and P. aeruginosa and Gram-positive bacteria, S. aureus, and C. diphtheriae using disc diffusion method. Some of these compounds have been found to exhibit excellent antibacterial activity.
