Check Digit Verification of cas no

The CAS Registry Mumber 71805-74-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,0 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71805-74:
(7*7)+(6*1)+(5*8)+(4*0)+(3*5)+(2*7)+(1*4)=128
128 % 10 = 8
So 71805-74-8 is a valid CAS Registry Number.

Formation of the Free Ion of Fluorenone Radical Anion ion Tetrahydrofuran by the Flash Photolysis of the Sulfonyl Carbanions

Nishi, Shin-ichi,Matsuda, Minoru

, p. 181 - 186 (2007/10/02)

The free ion of fluorenone radical anion (FIO).- was formed even in tetrahydrofuran (THF) by the flash photolysis of the alkali-metal salts of the sulfonyl carbanion in the presence of neutral FIO and this was attributed to the ion pair structure of the sulfonyl carbanions.
