Check Digit Verification of cas no

The CAS Registry Mumber 1609939-35-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,9,3 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1609939-35:
(9*1)+(8*6)+(7*0)+(6*9)+(5*9)+(4*3)+(3*9)+(2*3)+(1*5)=206
206 % 10 = 6
So 1609939-35-6 is a valid CAS Registry Number.

α-MsO/TsO/Cl ketones as oxidized alkyne equivalents: Redox-neutral rhodium(III)-catalyzed C-H activation for the synthesis of N-heterocycles

Yu, Da-Gang,De Azambuja, Francisco,Glorius, Frank

supporting information, p. 2754 - 2758 (2014/03/21)

α-Halo and pseudohalo ketones are used for the first time as C(sp3)-based electrophiles in transition-metal-catalyzed C-H activation and as oxidized alkyne equivalents in RhIII-catalyzed redox-neutral annulations to generate diverse N-heterocycles. This transformation is efficient and scalable. Due to the mild reaction conditions, a variety of functional groups could be tolerated. Who needs alkynes? α-Halo and pseudohalo ketones (as C(sp3)-based electrophiles) are utilized as oxidized alkyne equivalents in RhIII-catalyzed redox-neutral annulations to efficiently generate diverse N-heterocycles. Owing to the mild reaction conditions, a variety of functional groups are tolerated.
