Check Digit Verification of cas no

The CAS Registry Mumber 1139705-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,9,7,0 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1139705-23:
(9*1)+(8*1)+(7*3)+(6*9)+(5*7)+(4*0)+(3*5)+(2*2)+(1*3)=149
149 % 10 = 9
So 1139705-23-9 is a valid CAS Registry Number.

Imidazolylsulfonates: Electrophilic partners in cross-coupling reactions

Albaneze-Walker, Jennifer,Raju, Ravinder,Vance, Jennifer A.,Goodman, Andrew J.,Reeder, Michael R.,Liao, Jing,Maust, Mathew T.,Irish, Patrick A.,Espino, Peter,Andrews, David R.

, p. 1463 - 1466 (2009)

Aryl imidazolylsulfonates participate as electrophilic coupling partners in palladium-mediated cross-coupling reactions. The aryl imidazolylsulfonates display good stability while maintaining good reactivity in a variety of palladium-catalyzed coupling reactions. Imidazolylsulfonates are a practical and economic alternative to triflates.
