Check Digit Verification of cas no
The CAS Registry Mumber 143262-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,6 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143262-50:
(8*1)+(7*4)+(6*3)+(5*2)+(4*6)+(3*2)+(2*5)+(1*0)=104
104 % 10 = 4
So 143262-50-4 is a valid CAS Registry Number.

Benzimidazolo-diazepines from 1,3-dienes and arenediazocyanides through a 1,3,4-tri-aza-Cope rerrangement
Rousselle, Daniel,Ryckmans, Thomas,Viehe, Heinz G.
, p. 5249 - 5258 (2007/10/02)
Cyclic and bicyclic 1-cyano-2-arylhydrazines were prepared from arene diazocyanides and 1,3-dienes. Some of them rearrange at room temperature through a 1,3,4-tri-aza-Cope rearrangement, followed by an intramolecular cyclisation, to afford benzimidazolo-d
Tris-aza-cope rearrangement of bicyclic N-cyano-N'-vinyl or N'-arylhydrazines to imidazolo-diazepine derivatives
