Check Digit Verification of cas no
The CAS Registry Mumber 110809-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,8,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 110809-98:
(8*1)+(7*1)+(6*0)+(5*8)+(4*0)+(3*9)+(2*9)+(1*8)=108
108 % 10 = 8
So 110809-98-8 is a valid CAS Registry Number.

Synthesis of some 1,3,4-benzotriazepin-5(H)-one derivatives
Shailaja, G.,Reddy, P. S. N.
, p. 321 - 325 (2007/10/02)
Reaction of 1-(2-aminobenzoyl)-1-methylhydrazine (1) with n-butyraldehyde gives 2-n-propyl-1,2,3,4-tetrahydro-1,3,4-benzotriazepin-5(H)-one (2).With aromatic aldehydes, however, the corresponding hydrazones (3) are formed which, under thermal conditions,
