Check Digit Verification of cas no

The CAS Registry Mumber 1309570-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,5,7 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1309570-91:
(9*1)+(8*3)+(7*0)+(6*9)+(5*5)+(4*7)+(3*0)+(2*9)+(1*1)=159
159 % 10 = 9
So 1309570-91-9 is a valid CAS Registry Number.

Palladium(0)-catalyzed arylative dearomatization of phenols

Rousseaux, Sophie,Garcia-Fortanet, Jorge,Del Aguila Sanchez, Miguel Angel,Buchwald, Stephen L.

, p. 9282 - 9285 (2011)

The palladium-catalyzed arylative dearomatization of phenols to yield spirocyclohexadienone products in good to excellent yields has been developed. Preliminary results demonstrate that the formation of the spirocyclic all-carbon quaternary center can be accomplished with high levels of enantiocontrol (up to 91% ee).
