Check Digit Verification of cas no

The CAS Registry Mumber 17684-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,8 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17684-15:
(7*1)+(6*7)+(5*6)+(4*8)+(3*4)+(2*1)+(1*5)=130
130 % 10 = 0
So 17684-15-0 is a valid CAS Registry Number.

Synthesis of coumarins via PIDA/I2-mediated oxidative cyclization of substituted phenylacrylic acids

Li, Jinming,Chen, Huiyu,Zhang-Negrerie, Daisy,Du, Yunfei,Zhao, Kang

, p. 4311 - 4320 (2013/04/24)

A variety of functionalized coumarins were synthesized from substituted phenylacrylic acids via PIDA/I2-mediated and irradiation-promoted oxidative carbon-oxygen bond formation. Our studies show that the oxygen in the pendant carboxylic acid group cyclizes favorably to the aryl ring that is cis to it. The main advantages of this method include good functional group tolerance and the transition-metal-free characteristic. The Royal Society of Chemistry 2013.

Palladium-catalyzed intramolecular amidation of C(sp2)-H bonds: Synthesis of 4-aryl-2-quinolinones

Inamoto, Kiyofumi,Saito, Tadataka,Hiroya, Kou,Doi, Takayuki

supporting information; experimental part, p. 3900 - 3903 (2010/07/05)

Figure presented A catalytic synthetic approach for the synthesis of 2-quinolinone compounds through a Pd-catalyzed C(sp2)-H functionalization/intramolecular amidation sequence is described. The cyclization process efficiently proceeds in the p
