The CAS Registry Mumber 1233878-98-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,8,7 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1233878-98:
(9*1)+(8*2)+(7*3)+(6*3)+(5*8)+(4*7)+(3*8)+(2*9)+(1*8)=182
182 % 10 = 2
So 1233878-98-2 is a valid CAS Registry Number.

Selective addition of organolithium reagents to BF2-chelates of β-ketoesters

Stefane, Bogdan

supporting information; experimental part, p. 2900 - 2903 (2010/09/09)

A short, mild, and highly chemoselective addition of organolithium reagents to a BF2 complex of 3-oxopropanoates has been developed. The methodology allows straightforward preparation of various 1,3-dioxa-BF 2 complexes and subsequently leads to the formation of 1,3-diketones starting from the corresponding 3-oxopropanoates.
