Check Digit Verification of cas no

The CAS Registry Mumber 1442664-34-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,2,6,6 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1442664-34:
(9*1)+(8*4)+(7*4)+(6*2)+(5*6)+(4*6)+(3*4)+(2*3)+(1*4)=157
157 % 10 = 7

Synthesis of a 2(1 h)-pyridone library via rhodium-catalyzed formation of isomunchones

De, Subhasis,Chen, Lu,Zhang, Shuxing,Gilbertson, Scott R.

supporting information, p. 340 - 343 (2013/07/26)

Through the use of the dipolar cycloaddition of isomunchones with olefins the 2(1H)-pyridone ring system has been synthesized.(1) The use of different cyclization partners followed by diversification of the initial scaffold has provded libraries of 4-hydroxy-2(1H)-pyridones. There are no examples of this ring system in either PubChem or the MLSMR
