Check Digit Verification of cas no

The CAS Registry Mumber 1043905-80-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,3,9,0 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1043905-80:
(9*1)+(8*0)+(7*4)+(6*3)+(5*9)+(4*0)+(3*5)+(2*8)+(1*0)=131
131 % 10 = 1
So 1043905-80-1 is a valid CAS Registry Number.

1-Butyl-3-methylimidazol-2-ylidene Borane: A Readily Available, Liquid N-Heterocyclic Carbene Borane Reagent

Bolt, Daniel A.,Curran, Dennis P.

, p. 13746 - 13750 (2017)

1-Butyl-3-methylimidazol-2-ylidene borane has been synthesized directly from two inexpensive commercial reagents: 1-butyl-3-methylimidazolium bromide and sodium borohydride. This NHC-borane reagent is a stable, free-flowing liquid that shows promise for use in radical, ionic, and metal-catalyzed reactions.

Complexes of borane and N-heterocyclic carbenes: A new class of radical hydrogen atom donor

Ueng, Shau-Hua,Brahmi, Malika Makhlouf,Derat, Etienne,Fensterbank, Louis,Lacote, Emmanuel,Malacria, Max,Curran, Dennis P.

supporting information; experimental part, p. 10082 - 10083 (2009/02/04)

Calculations suggest that complexes of borane with N-heterocyclic carbenes (NHC) have B-H bond dissocation energies more then 20 kcal/mol less than free borane, diborane, borane-THF, and related complexes. Values are in the range of popular radical hydrogen atom donors like tin hydrides (70-80 kcal/mol). The resulting prediction that NHC borane complexes could be used as radical hydrogen atom donors was verified by radical deoxygenations of xanthates by using either AIBN or triethylborane as initiator.
