Check Digit Verification of cas no

The CAS Registry Mumber 108103-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,0 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 108103-33:
(8*1)+(7*0)+(6*8)+(5*1)+(4*0)+(3*3)+(2*3)+(1*3)=79
79 % 10 = 9
So 108103-33-9 is a valid CAS Registry Number.

Reductive Molybdenum-Catalyzed Direct Amination of Boronic Acids with Nitro Compounds

Suárez-Pantiga, Samuel,Hernández-Ruiz, Raquel,Virumbrales, Cintia,Pedrosa, María R.,Sanz, Roberto

supporting information, p. 2129 - 2133 (2019/01/25)

The synthesis of aromatic amines is of utmost importance in a wide range of chemical contexts. We report a direct amination of boronic acids with nitro compounds to yield (hetero)aryl amines. The novel combination of a dioxomolybdenum(VI) catalyst and triphenylphosphine as inexpensive reductant has revealed to be decisive to achieve this new C?N coupling. Our methodology has proven to be scalable, air and moisture tolerant, highly chemoselective and engages both aliphatic and aromatic nitro compounds. Moreover, this general and step-economical synthesis of aromatic secondary amines showcases orthogonality to other aromatic amine syntheses as it tolerates aryl halides and carbonyl compounds.
