Check Digit Verification of cas no

The CAS Registry Mumber 253345-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,3,4 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 253345-81:
(8*2)+(7*5)+(6*3)+(5*3)+(4*4)+(3*5)+(2*8)+(1*1)=132
132 % 10 = 2
So 253345-81-2 is a valid CAS Registry Number.

Diversified synthesis of novel quinoline and dibenzo thiazepine derivatives using known active intermediates

Sharada,Satyanarayana Reddy,Sammaiah,Sumalatha

, p. 7959 - 7966 (2013)

The novel drug development to control resisting infections in conventional drug therapy is a need of today. Few antiulcer relative derivatives developed by approaching convergent synthesis. The derivatives synthesized successfully are dibenzo thiazepine-pyridine (SLN11-SLN15) and benzimidazole-hydroquinoline based derivatives (SLN16-SLN20). It involved the coupling through microwave, sonication and conventional techniques at final step. The efficient technology identified as sonication technique basically time and yield. The reported compounds were structural characterized by elemental analysis and spectral studies such as 1H, 13C NMR and MS.
