Check Digit Verification of cas no

The CAS Registry Mumber 827027-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,7,0,2 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 827027-40:
(8*8)+(7*2)+(6*7)+(5*0)+(4*2)+(3*7)+(2*4)+(1*0)=157
157 % 10 = 7
So 827027-40-7 is a valid CAS Registry Number.

Exceptional efficiency of palladium nanoparticle catalyzed Heck cross-coupling in binary task specific ionic liquids

Hassine, Fatima,Pucheault, Mathieu,Vaultier, Michel

, p. 671 - 679 (2012/04/04)

The utilization of the task specific onium salt supported substrates in ionic liquids as solvents (i.e., binary task specific ionic liquids) for palladium nanoparticle catalyzed Heck cross-coupling reactions is presented. Adequate substrates have been prepared and used leading to expected products in very high yields. Exceptionally high turnover (TON = 940,000, TOF = 208,000) can be achieved taking advantages of this combination. Additional advantages of this technology reside in the monitoring of the reaction and purification of products after degrafting which are simplified to the extreme.
