Check Digit Verification of cas no
The CAS Registry Mumber 197454-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,4,5 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 197454-20:
(8*1)+(7*9)+(6*7)+(5*4)+(4*5)+(3*4)+(2*2)+(1*0)=169
169 % 10 = 9
So 197454-20-9 is a valid CAS Registry Number.

HIGHLY ENANTIOSELECTIVE ALDOL REACTION OF METHYL KETONES VIA CHIRAL STANNOUS AZAENOLATES

, p. 1399 - 1402 (2007/10/02)
Chiral 1,3-oxazolidines are readily prepared from methyl ketones and chiral norephedrine.Formation of stannous azaenolates from the oxazolidines and reaction with aldehydes followed by removal of the chiral auxiliary lead to the aldol products in high level of enantiomeric putity.
