Check Digit Verification of cas no
The CAS Registry Mumber 127020-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,2 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127020-11:
(8*1)+(7*2)+(6*7)+(5*0)+(4*2)+(3*0)+(2*1)+(1*1)=75
75 % 10 = 5
So 127020-11-5 is a valid CAS Registry Number.

Synthetic routes to indenothiophene, indenopyran and fluorenone derivatives
El-Taweel,Sofan,Ayaad,Abu El-Maati,El-Agamey
, p. 448 - 458 (2007/10/03)
Reaction of 3-arylaminoindene (3) with sulphur and malononitrile gave indenothiophenes (5). Hydrolysis of (5) gave (6). Condensation of (3) with malononitrile yielded (4). Treating (4d) with arylidenes (2a) afforded fluoreneimines (9). Reaction of (3) with (2a-1) yielded indenopyran (14). Hydrolysis of (14) gave (15). Also, reaction of hydrazone (16) with (2) yielded indenopyran (18), which was hydrolysed to (15). Treatment of (16) with sulphur and malononitrile or ethyl cyanoacetate afforded indenothiophen (19). Hydrolysis of (19) yielded (6). Treating indanedione dimer (22) with aromatic aldehydes and (2) afforded the arylidenes (23) and fluorenones (25) respectively.
