Check Digit Verification of cas no

The CAS Registry Mumber 1613722-64-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,3,7,2 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1613722-64:
(9*1)+(8*6)+(7*1)+(6*3)+(5*7)+(4*2)+(3*2)+(2*6)+(1*4)=147
147 % 10 = 7
So 1613722-64-7 is a valid CAS Registry Number.

A simple heterocyclic fusion reaction and its application for expeditious syntheses of rutaecarpine and its analogs

Huang, Guozheng,Roos, Dominika,Stadtmüller, Patricia,Decker, Michael

, p. 3607 - 3609 (2014)

In the search for new inhibitors of cholinesterases, a simple heterocyclic fusion reaction of isatoic anhydride 8 and 3,4-dihydroisoquinoline 22 was discovered which involves a spontaneous dehydrogenation upon heating. Applying the reaction, the bioactive natural alkaloid rutaecarpine and several substituted derivatives out of tryptamines and anthranilic acids or isatoic anhydrides, respectively, can be synthesized without tedious chromatographic purification. This provides simple and fast access to larger amounts of compounds with this privileged structure in medicinal chemistry.
