Check Digit Verification of cas no

The CAS Registry Mumber 1092654-41-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,2,6,5 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1092654-41:
(9*1)+(8*0)+(7*9)+(6*2)+(5*6)+(4*5)+(3*4)+(2*4)+(1*1)=155
155 % 10 = 5
So 1092654-41-5 is a valid CAS Registry Number.

Enantio- and diastereoselective Betti/aza-michael sequence: Single operated preparation of chiral 1,3-disubstituted isoindolines

Takizawa, Shinobu,Sako, Makoto,Abozeid, Mohamed Ahmed,Kishi, Kenta,Wathsala,Hirata, Shuichi,Murai, Kenichi,Fujioka, Hiromichi,Sasai, Hiroaki

, p. 5426 - 5429 (2017)

The first enantio- and diastereoselective Betti/intramolecular aza-Michael sequence carried out using a C3-symmetric chiral trisimidazoline organocatalyst is reported. The reaction of phenols and N-tosylimines bearing a Michael acceptor moiety afforded densely functionalized 1,3-disub-stituted isoindolines bearing two stereogenic centers as single diastereomers in high yields (=93%) and excellent enantiose-lectivities (=99.9%).
