Calculate Digit Verification of CAS Registry Number 118684-37:
(8*1)+(7*1)+(6*8)+(5*6)+(4*8)+(3*4)+(2*3)+(1*7)=150
150 % 10 = 0
So 118684-37-0 is a valid CAS Registry Number.

An improved transient method for the synthesis of N-benzoylated nucleosides

Zhu, Xue-Feng,Williams Jr., Howard J.,Scott, A. Ian

, p. 1233 - 1243 (2007/10/03)

The Jones' transient method for the synthesis of N-benzoylated nucleosides is improved by reducing the amounts of chlorotrimethylsilane (TMSCl) and benzoyl chloride to nearly equivalent quantities. The easy work-up and high yields of products are the major advantages of this approach. Jones' method is further simplified by omitting the addition of ammonium hydroxide. The utility of this modification for the preparation of some useful protected nucleosides is also presented.
