Check Digit Verification of cas no
The CAS Registry Mumber 18097-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,9 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18097-52:
(7*1)+(6*8)+(5*0)+(4*9)+(3*7)+(2*5)+(1*2)=124
124 % 10 = 4
So 18097-52-4 is a valid CAS Registry Number.

Mechanism of selective formation of 2-amino-substituted 1,4-benzodiazepin-4-oxides and 2-aminomethyl substituted quinazolin-3-oxides from chloromethyl quinazolin-N-oxides indications from perturbation theory

, p. 77 - 84 (2007/10/02)
The o-amino-acetophenone and -benzophenone oximes 1a-c react with chloroacetyl chloride giving the 2-chloromethyl-quinazoline-3-oxides 6a-c. The mechanism is explained using the perturbation theory. With ammonia and N-prim. aliphatic amines, compounds 6a-c yield 1,4-benzodiazepines 16 and 17 as ring-enlarged products, with aromatic and with N-sec. aliphatic amines, quinazoline derivatives 10-13 are formed. The constitution of the heterocycles is proved by nmr spectroscopic methods. Selective formation of the heterocyclic products is explained with the relative thermodynamic stability of the corresponding 2-adducts 14.
