100390-89-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100390-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,3,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 100390-89:
(8*1)+(7*0)+(6*0)+(5*3)+(4*9)+(3*0)+(2*8)+(1*9)=84
84 % 10 = 4
So 100390-89-4 is a valid CAS Registry Number.

Frustrated Lewis Pair Catalyzed Hydrogenation of Amides: Halides as Active Lewis Base in the Metal-Free Hydrogen Activation

Sitte, Nikolai A.,Bursch, Markus,Grimme, Stefan,Paradies, Jan

supporting information, p. 159 - 162 (2019/01/04)

A method for the metal-free reduction of carboxylic amides using oxalyl chloride as an activating agent and hydrogen as the final reductant is introduced. The reaction proceeds via the hydrogen splitting by B(2,6-F2-C6H3)3 in combination with chloride as the Lewis base. Density functional theory calculations support the unprecedented role of halides as active Lewis base components in the frustrated Lewis pair mediated hydrogen activation. The reaction displays broad substrate scope for tertiary benzoic acid amides and α-branched carboxamides.
