Check Digit Verification of cas no

The CAS Registry Mumber 220714-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,7,1 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220714-69:
(8*2)+(7*2)+(6*0)+(5*7)+(4*1)+(3*4)+(2*6)+(1*9)=102
102 % 10 = 2
So 220714-69-2 is a valid CAS Registry Number.

Iridium-catalyzed enantioselective addition of an: N -methyl C-H bond to α-trifluoromethylstyrenes via C-H activation

Yamauchi, Daisuke,Nakamura, Ikumi,Nishimura, Takahiro

supporting information, p. 11787 - 11790 (2021/11/30)

The Ir-catalyzed enantioselective addition of an N-methyl C-H bond of 2-(methylamino)pyridine derivatives to α-trifluoromethylstyrenes proceeded via C-H activation to give chiral γ-branched amine derivatives having a trifluoromethyl-substituted stereocenter. It was found that a bulky and electron-withdrawing group at the 3-position of 2-(methylamino)pyridines was necessary for the present C-H addition reaction catalyzed by a cationic iridium/chiral bisphosphine complex.
