Check Digit Verification of cas no

The CAS Registry Mumber 24337-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,3,3 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24337-53:
(7*2)+(6*4)+(5*3)+(4*3)+(3*7)+(2*5)+(1*3)=99
99 % 10 = 9
So 24337-53-9 is a valid CAS Registry Number.

Functionalized organolithium compounds of DTBB-catalyzed sulfur-lithium exchange

Foubelo, Francisco,Gutiérrez, Ana,Yus, Miguel

, p. 503 - 514 (2007/10/03)

The successive reaction of β- or γ-hydroxy or amino phenyl thioethers (1,4) with butyllithium and an excess of lithium powder in the presence of a catalytic amount of DTBB in THF at - 78°C leads to the formation of the corresponding β- or γ-functionalized organolithium compounds 2 or 5, respectively, which by treatment with different electrophiles [D2O, t- BuCHO, PhCHO, Me2CO, (CH2)4CO, (CH2)5CO] at temperatures ranging between - 78°C and room temperature yields, after hydrolysis with water, the expected functionalized alcohols or amines 3 or 6, respectively, in a completely regioselective manner.
