1271337-11-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1271337-11-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,1,3,3 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1271337-11:
(9*1)+(8*2)+(7*7)+(6*1)+(5*3)+(4*3)+(3*7)+(2*1)+(1*1)=131
131 % 10 = 1
So 1271337-11-1 is a valid CAS Registry Number.

Palladium- and nickel-catalyzed aminations of aryl imidazolylsulfonates and sulfamates
Ackermann, Lutz,Sandmann, Rene,Song, Weifeng
, p. 1784 - 1786 (2011)
A nickel complex derived from dppf, along with NaOt-Bu as the base, allowed for challenging aminations of aryl sulfamates. An improved functional group tolerance is observed in novel palladium-catalyzed aminations of imidazolylsulfonates with rac-BINAP as the ligand.
