Check Digit Verification of cas no

The CAS Registry Mumber 99789-33-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99789-33:
(7*9)+(6*9)+(5*7)+(4*8)+(3*9)+(2*3)+(1*3)=220
220 % 10 = 0
So 99789-33-0 is a valid CAS Registry Number.

Tetrabutylammonium phenoxide induced reaction of silyl nucleophiles

Capperucci, Antonella,Tiberi, Caterina,Pollicino, Salvatore,Degl'Innocenti, Alessandro

experimental part, p. 2808 - 2810 (2009/09/30)

Reaction of silyl dithiolanes with electrophiles can be efficiently promoted by catalytic amounts of tetrabutylammonium phenoxide (PhONn-Bu4), leading to a convenient access to functionalized dithiolanes. PhONn-Bu4 proved effective a

Regioselective ring opening of epoxides by nucleophiles mediated by lithium bistrifluoromethanesulfonimide

Cossy, Janine,Bellosta, Véronique,Hamoir, Claire,Desmurs, Jean-Roger

, p. 7083 - 7086 (2007/10/03)

In the presence of LiNTf2, epoxides undergo ring opening with high regioselectivity and in good yield when they are treated with nucleophiles such as amines, hydrazines and thiophenol.
