Check Digit Verification of cas no

The CAS Registry Mumber 1133809-98-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,8,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1133809-98:
(9*1)+(8*1)+(7*3)+(6*3)+(5*8)+(4*0)+(3*9)+(2*9)+(1*8)=149
149 % 10 = 9
So 1133809-98-9 is a valid CAS Registry Number.

Photochromism of dihydroindolizines. Part 12: synthesis and photochromism of novel π-conjugated rigid dihydroindolizines as potential molecular electronic devices

Ahmed, Saleh Abdel-Mgeed

scheme or table, p. 1373 - 1388 (2009/05/09)

Novel carbon-rich photochromic dihydroindolizine DHI derivatives and new spirocyclopropenes have been synthesized. Three alternative synthetic pathways for the synthesis of DHI 10 have been established. Different Sonogashira-mediated coupling reactions ha
