Check Digit Verification of cas no

The CAS Registry Mumber 113503-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,0 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113503-81:
(8*1)+(7*1)+(6*3)+(5*5)+(4*0)+(3*3)+(2*8)+(1*1)=84
84 % 10 = 4
So 113503-81-4 is a valid CAS Registry Number.

A green approach for highly regioselective syntheses of furo[3,2-h]quinolines in aqueous medium

Sarkar, Swarbhanu,Pal, Rammyani,Chatterjee, Nivedita,Dutta, Samrat,Naskar, Subhendu,Sen, Asish Kumar

, p. 3805 - 3809 (2013/07/27)

An environmentally benign, high yielding, and operationally simple protocol has been developed for the regioselective synthesis of furo[3,2-h]quinolines in aqueous micellar medium involving Cu-free domino Sonogashira reaction followed by 5-endo-dig-cyclization of substituted 8-hydroxyquinolines and terminal alkyne by using Pd(C6H5CN)Cl2 as catalyst and 2-pyridinecarboxaldehyde methylphenyl hydrazone as ligand under aerobic condition.
