Check Digit Verification of cas no

The CAS Registry Mumber 1246956-27-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,9,5 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1246956-27:
(9*1)+(8*2)+(7*4)+(6*6)+(5*9)+(4*5)+(3*6)+(2*2)+(1*7)=183
183 % 10 = 3
So 1246956-27-3 is a valid CAS Registry Number.

Enantioselective friedel-crafts alkylation of indoles with trifluoroethylidene malonates by copper-bis(oxazoline) complexes: Construction of trifluoromethyl-substituted stereogenic tertiary carbon center

Wen, Lele,Shen, Qilong,Wan, Xiaolong,Lu, Long

, p. 2282 - 2285 (2011)

An enantioselective alkylation of indoles with trifluoroethylidene malonates catalyzed by copper(II)-bis (oxazoline) complexes has been developed. The expected adducts with a stereogenic tertiary carbon center bearing a trifluoromethyl group were obtained

Enantioselective organocatalytic Michael addition of aldehydes to trifluoroethylidene malonates
