Check Digit Verification of cas no

The CAS Registry Mumber 20473-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,7 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20473-78:
(7*2)+(6*0)+(5*4)+(4*7)+(3*3)+(2*7)+(1*8)=93
93 % 10 = 3
So 20473-78-3 is a valid CAS Registry Number.

Lithium trifluoromethanesulfonate (LiOTf) as a recyclable catalyst for highly efficient acetylation of alcohols and diacetylation of aldehydes under mild and neutral reaction conditions

Karimi, Babak,Maleki, Jafar

, p. 4951 - 4954 (2007/10/03)

A variety of alcohols and aldehydes were reacted with acetic anhydride at room temperature in the presence of a catalytic amount of lithium triflate (LiOTf) to produce the corresponding esters and 1,1-diacetates, respectively, in good to excellent yields under essentially neutral reaction conditions. Sensitive functional groups such as PhCO2-, OMe, and OTBDMS ethers survived intact under the described reaction conditions.
