Check Digit Verification of cas no

The CAS Registry Mumber 80379-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,7 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 80379-89:
(7*8)+(6*0)+(5*3)+(4*7)+(3*9)+(2*8)+(1*9)=151
151 % 10 = 1
So 80379-89-1 is a valid CAS Registry Number.

Nickel-Catalyzed Stereo- and Enantioselective Cross-Coupling of gem-Difluoroalkenes with Carbon Electrophiles by C?F Bond Activation

Zhu, Ziqi,Lin, Lin,Xiao, Jieshuai,Shi, Zhuangzhi

, (2021/12/27)

Stereo- and enantioselective cross-electrophile coupling involving C?F bond activation is reported. Treatment of gem-difluoroalkenes with racemic benzyl electrophiles in the presence of a chiral nickel complex using B2pin2 as a stoichiometric reductant allows the construction of a C(sp2)?C(sp3) bond under mild conditions, affording a broad range of monofluoroalkenes bearing stereogenic allylic centers. Initial mechanistic studies indicate that a radical chain pathway may be operating, wherein the ester group in the gem-difluoroalkene promotes C?F bond activation through oxidative addition to a Ni species.
