Check Digit Verification of cas no
The CAS Registry Mumber 127015-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,1 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127015-49:
(8*1)+(7*2)+(6*7)+(5*0)+(4*1)+(3*5)+(2*4)+(1*9)=100
100 % 10 = 0
So 127015-49-0 is a valid CAS Registry Number.

oxotitanium. A Chemoselective and Efficient Catalyst for Aldol-type Reaction of Ketene Silyl Acetals with Aldehydes
Hara, Ryuichiro,Mukaiyama, Teruaki
, p. 1909 - 1912 (1989)
In the presence of catalytic amount of oxotitanium, ketene silyl acetals smoothly react with aldehydes to afford the corresponding β-hydroxy carboxylic esters in good yields under mild conditions.According to this procedure, a
