Check Digit Verification of cas no
The CAS Registry Mumber 143237-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,3 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143237-11:
(8*1)+(7*4)+(6*3)+(5*2)+(4*3)+(3*7)+(2*1)+(1*1)=100
100 % 10 = 0
So 143237-11-0 is a valid CAS Registry Number.

The highly diastereoselective Mukaiyama-Michael reaction has been realized by use of O,S-ketene silyl acetals. Of special importance in this reaction is the effective tuning of the stereochemical course simply by changing the double bond geometry of ketene silyl acetals. Thus, both syn- and anti-Michael adducts can be obtained on the synthetically useful levels of stereochemical purity.
The design of diastereoselective Mukaiyama-Michael reaction of ketene silyl acetal

The highly diastereoselective Mukaiyama-Michael reaction has been designed. Suppression of an electron-transfer process is crucial for this purpose and the following conditions should be satisfied. (1) TiCl4 is employed as a Lewis acid. (2) Ketene silyl acetals have bulky siloxy and/or alkoxy group(s). (3) α-Enones have a bulky acyl group. The excellent syn- selectivity up to a 99:1 ratio is attained under these conditions. The selectivity is reversed to the anti-preference upon decreasing the size of the alkoxy group.
