1027211-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027211-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,2,1 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1027211-99:
(9*1)+(8*0)+(7*2)+(6*7)+(5*2)+(4*1)+(3*1)+(2*9)+(1*9)=109
109 % 10 = 9
So 1027211-99-9 is a valid CAS Registry Number.

Catalytic enantioselective Mukaiyama-Michael reaction of 2-(trimethylsilyloxy)furan with α′-phenylsulfonyl enones
Yang, Hyeyeon,Kim, Sunggak
, p. 555 - 560 (2008)
The Mukaiyama-Michael reaction of 2-(trimethylsilyloxy)furan with α′-phenylsulfonyl enones using bis(oxazoline)-copper(II) complexes as chiral catalyst provides the γ-butenolides in high enantio- and diastereoselectivity. This approach is very useful for
