Check Digit Verification of cas no

The CAS Registry Mumber 13721-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,2 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13721-20:
(7*1)+(6*3)+(5*7)+(4*2)+(3*1)+(2*2)+(1*0)=75
75 % 10 = 5
So 13721-20-5 is a valid CAS Registry Number.

Preparation method of phenylacetic acid type compound

-

Paragraph 0134-0150, (2019/02/21)

The invention discloses a preparation method of a phenylacetic acid type compound. The preparation method of the phenylacetic acid type compound I comprises the following steps that in a solvent and aCO gas phase system, a benzyl halide type compound II, pyridine-2-cobalt carboxylate, palladium acetate and alkaline neutralizers take carbonylation reaction to obtain the phenylacetic acid type compound I. A mixed catalytic system has a synergistic effect; the whole use quantity of catalysts is greatly reduced. When the mixed catalyst is used, a better catalytic effect can be achieved; the characteristics of easily obtaining the catalyst, avoiding the production safety risk of toxic three wastes and the like, reducing the reaction pressure, realizing mild reaction conditions, reducing the production risk, facilitating the production and the like are realized. The formulas are shown in description.

Exalted resonance demands in the substituent effects on the acetolyses of 2-arylethyl trifluoromethanesulfonates destabilized by cn and cf3 groups

Usui, Satoshi,Tsuboya, Shoko,Umezawa, Yukthiro,Hazama, Ken,Okamura, Mutsuo

experimental part, p. 254 - 260 (2009/05/30)

Substituent effects on the acetolysis rates of 2-aryl-l-cyano-l- (trifluoromethyl)ethyl trifluoromethanesulfonates (α-OTf) and 2-aryl-2-cyano-2-(trifluoromethyl)ethyl trifluoromethanesulfonates (ss-OTf) were investigated by using LArSR equation. The obtained p and r+ values were p = -3.28, r+ = 0.98 and p = -3.48,r+ = 0.93 for the acetolysis of α-OTf and ss-OΥi, respectively. The obtained p values are comparable to those for typical aryl-assisted solvolyses, but the r+ values are much larger. The large r+ values suggest that the ester bond cleavages in the deactivated aryl-assisted solvolyses are assisted by the strong participation of the ss-aryl group.
