Check Digit Verification of cas no
The CAS Registry Mumber 1204769-77-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,7,6 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1204769-77:
(9*1)+(8*2)+(7*0)+(6*4)+(5*7)+(4*6)+(3*9)+(2*7)+(1*7)=156
156 % 10 = 6
So 1204769-77-6 is a valid CAS Registry Number.

A general asymmetric aldol reaction of silyl ketene acetals derived from simple esters to aryl α-keto esters
Le Engers, Julie,Pagenkopf, Brian L.
, p. 6109 - 6111 (2009)
A general, method for the enantloselective addition of O,Oketene silyl acetals made from simple esters to α-keto esters catalyzed by a CuCl 2·bis(oxazoline) complex is reported that overcomes the limitations of the classic aldol reaction, such
