Check Digit Verification of cas no

The CAS Registry Mumber 1588513-04-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,8,5,1 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1588513-04:
(9*1)+(8*5)+(7*8)+(6*8)+(5*5)+(4*1)+(3*3)+(2*0)+(1*4)=195
195 % 10 = 5
So 1588513-04-5 is a valid CAS Registry Number.

Regioselective piperidine-catalyzed tandem imination-isocyanate annulation to fused tricyclic triazines

Barve, Indrajeet J.,Chen, Chih-Hau,Kao, Chih-Hsien,Sun, Chung-Ming

, p. 244 - 249 (2014/06/09)

A novel tandem imination-isocyanate-mediated annulation was explored. Ionic liquid-immobilized 2-aminobenzimidazoles react sequentially with aldehydes and isocyanates to give highly functionalized benzimidazole-embedded triazines. The second-stage transformation revealed that the formation of triazinone functionality is entirely regioselective to allow rapid assembly of biologically interesting tricyclic skeletons. In conjunction with the application of microwave irradiation and IL support, this method provides an efficient route to access substituted benzoimidazotriazines.
