Check Digit Verification of cas no

The CAS Registry Mumber 1423027-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,3,0,2 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1423027-23:
(9*1)+(8*4)+(7*2)+(6*3)+(5*0)+(4*2)+(3*7)+(2*2)+(1*3)=109
109 % 10 = 9
So 1423027-23-9 is a valid CAS Registry Number.

Novel synthesis of 4,4-difluoropyrido[4,3-b]indoles via intramolecular Heck reaction

Madaiah,Prashanth,Revanasiddappa

supporting information, p. 1424 - 1427 (2013/04/23)

Various difluoropyridoindoles were synthesized via a palladium-catalyzed intramolecular Heck reaction as a key step. Thus, ortho-bromoanilines and difluoropiperidinone were treated with (PPh3)2PdCl 2 and base in pyridine to give the regioselective cyclized heterocycles in modest to satisfactory yields. Copyright
