The CAS Registry Mumber 1256564-27-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,5,6 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1256564-27:
(9*1)+(8*2)+(7*5)+(6*6)+(5*5)+(4*6)+(3*4)+(2*2)+(1*7)=168
168 % 10 = 8

One pot synthesis of substituted [1,2,4]-Triazolo [1',2':1,2]pyrimido [6,5-b]-quinoline and its antibacterial activity

Joshi, Ratnadeep S.,Mandhane, Priyanka G.,Chate, Asha V.,Khan, Wajid,Gill, Charansingh H.

experimental part, p. 2341 - 2344 (2010/11/16)

A convenient synthesis of substituted [1,2,4]-triazolo [1',2':1,2] pyrimido[6,5-b]-quinoline 4(a-i) from substituted 2-chloroquinoline-3- carbaldehyde 1(a-i) and 4H-1,2,4-triazol-3-amine 2 by using SiO 2/K2CO3 under microwave irradiation. This method affords the [1,2,4]-Triazolo [1',2':1,2]pyrimido[6,5-b]-quinoline 4(a-i) under the influence of microwave irradiation in solvent-free conditions within short span (12 - 20 min), & gaves excellent yields (89 -95%). All the synthesized compounds were further screened for their antibacterial activities. Some of our compounds showed excellent antibacterial activities against control drugs.
