Check Digit Verification of cas no

The CAS Registry Mumber 862158-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,1,5 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 862158-38:
(8*8)+(7*6)+(6*2)+(5*1)+(4*5)+(3*8)+(2*3)+(1*8)=181
181 % 10 = 1
So 862158-38-1 is a valid CAS Registry Number.

Copper-Catalyzed Regioselective Ring-Opening Hydroamination of Methylenecyclopropanes

Nishikawa, Daiki,Sakae, Ryosuke,Miki, Yuya,Hirano, Koji,Miura, Masahiro

, p. 12128 - 12134 (2016/12/23)

A copper-catalyzed ring-opening hydroamination of methylenecyclopropanes with polymethylhydrosiloxane and O-benzoylhydroxylamines has been developed. The cyclopropane C-C bond cleavage occurs selectively at the more congested proximal position, and the corresponding homoallylamines are obtained in good to excellent yields. The umpolung electrophilic amination strategy with the hydroxylamine derivatives can provide a new reaction mode of methylenecyclopropanes in the catalytic hydroamination reaction.
