36625-33-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 36625-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,6,2 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 36625-33:
(7*3)+(6*6)+(5*6)+(4*2)+(3*5)+(2*3)+(1*3)=119
119 % 10 = 9
So 36625-33-9 is a valid CAS Registry Number.

Vinyliminophosphorane-mediated preparation of 2-arylquinoline and 4-aryl-1-azaanthraquinone derivatives. X-Ray crystal structure of 1,2-dihydro-3H-indazolo[2,3-a]quinolin-4-one

The reaction of the iminophosphorane derived from 3-azidocyclohexan-2-enone with substituted cinnamyl aldehydes affords 2-aryl-tetrahydroquinoline derivatives, which are easily converted into 2-arylquinolones. By contrast, iminophosphorane derived from 2-azidocyclohex-2-enone reacts only with α,β-unsaturated aldehydes without substituent at β-position to give 5,6-dihydro-8(7H)quinolinones. The iminophosphorane derived from 2-azido-1,4-naphthoquinone reacts with substituted cinnamyl aldehydes providing directly 4-aryl-1-azaanthraquinones. The crystal and molecular structure of 1,2-dihydro-3H-indazolo[2,3-a]quinolin-4-ono has been solved by X-Ray analysis.
