Check Digit Verification of cas no

The CAS Registry Mumber 1629894-53-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,9,8,9 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1629894-53:
(9*1)+(8*6)+(7*2)+(6*9)+(5*8)+(4*9)+(3*4)+(2*5)+(1*3)=226
226 % 10 = 6
So 1629894-53-6 is a valid CAS Registry Number.

Functionalization of α-C(sp3)?H Bonds in Amides Using Radical Translocating Arylating Groups

Radhoff, Niklas,Studer, Armido

, p. 3561 - 3565 (2021)

α-C?H arylation of N-alkylamides using 2-iodoarylsulfonyl radical translocating arylating (RTA) groups is reported. The method allows the construction of α-quaternary carbon centers in amides. Various mono- and disubstituted RTA-groups are applied to the arylation of primary, secondary, and tertiary α-C(sp3)?H-bonds. These radical transformations proceed in good to excellent yields and the cascades comprise a 1,6-hydrogen atom transfer, followed by a 1,4-aryl migration with subsequent SO2 extrusion.
