Check Digit Verification of cas no

The CAS Registry Mumber 40091-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,9 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40091-57:
(7*4)+(6*0)+(5*0)+(4*9)+(3*1)+(2*5)+(1*7)=84
84 % 10 = 4
So 40091-57-4 is a valid CAS Registry Number.

A formal anti-Markovnikov hydroalkoxylation of allylic alcohols with a ruthenium catalyst

Nakamura, Yushi,Ohta, Tetsuo,Oe, Yohei

supporting information, p. 288 - 291 (2018/02/14)

Hydroalkoxylation of C-C double bonds was achieved through the use of a ruthenium catalyst. The reaction of allylic alcohols with nucleophilic alcohols was carried out in the presence of a ruthenium catalyst prepared by RuClH(CO)(PPh3)3 and 2,6-bis(n-butyliminomethyl)-4-(piperidin-1-yl)pyridine under mild reaction conditions to afford the corresponding γ-alkoxypropanols in good yield.
