Check Digit Verification of cas no
The CAS Registry Mumber 20981-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,8 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20981-09:
(7*2)+(6*0)+(5*9)+(4*8)+(3*1)+(2*0)+(1*9)=103
103 % 10 = 3
So 20981-09-3 is a valid CAS Registry Number.

Lead Tetraacetate Induced Ring Transformation of 6,7-Dihydro-6-arylquinazolino-benzotriazepin-9(5H)-ones
Reddy, P. S. N.,Raju, Ch. Naga
, p. 983 - 984 (2007/10/02)
6,7-Dihydro-6-arylquinazolinobenzotriazepin-9(5H)-ones (3a-f) undergo ring transformation when refluxed with lead tetraacetate in benzene to give quinazolinobenzotriazin-8-one (4) along with the corresponding benzylidene diacetates (5a-f).Structural assignements are based on spectral data (UV, IR, PMR and mass).
