The CAS Registry Mumber 34790-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,9 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34790-20:
(7*3)+(6*4)+(5*7)+(4*9)+(3*0)+(2*2)+(1*0)=120
120 % 10 = 0
So 34790-20-0 is a valid CAS Registry Number.

-

, (2008/06/13)

Quinazoline derivatives represented by the formula SPC1 Wherein R1 and R2 are individually a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a nitro group, a lower alkylthio group or a lower alkylsulfonyl group; R3 is a hydrogen atom, a lower alkyl group, a lower cycloalkyl group, a napthyl group, a furyl group or a thienyl group; R4 is a lower cycloalkyl group or a trihalomethyl group; and n is an integer of 1 to 3, are novel compounds and have excellent pharmacological properties, particularly as anti-inflammatory and analgesic effects with low toxicity. They can be prepared by treating with ammonia a trihaloacetamidophenylketone derivative of the formula, SPC2 Wherein R1, R2 and R3 are as defined above; R is a hydrogen atom or a group of the formula --Cn H2n --R4 ; and X is a halogen atom.
