Check Digit Verification of cas no

The CAS Registry Mumber 180037-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,0,3 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 180037-06:
(8*1)+(7*8)+(6*0)+(5*0)+(4*3)+(3*7)+(2*0)+(1*6)=103
103 % 10 = 3
So 180037-06-3 is a valid CAS Registry Number.

Investigations on the pathway of the fluorescence reaction of a pharmaceutically important 1,3-diamine with 2-benzoylbenzaldehyde

Troschuetz, Reinhard,Heinemann, Oliver

, p. 267 - 269 (1996)

The reaction of 2-benzoylbenzaldehyde (1) with primary diamine 2, generated by rearrangement and hydrolysis of Oxazepam, in CD3OD leads to intensely fluorescing deuterated isoindoloquinazolines 3 and 4. Reduction of ethyl 2-benzoylbenzoate (5) with LiAlD4 followed by oxidation with MnO2 yields 2-benzoyl-benz[D]aldehyde (7). The condensation of 7 with diamine 2 leads to isoindoloquinazoline 12, free of deuterium. On the basis of these experiments a plausible pathway is proposed for the 'fluorescence reaction'.
