213198-15-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 213198-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,1,9 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 213198-15:
(8*2)+(7*1)+(6*3)+(5*1)+(4*9)+(3*8)+(2*1)+(1*5)=113
113 % 10 = 3
So 213198-15-3 is a valid CAS Registry Number.

Stereoselective synthesis of enantiomerically pure piperidine derivatives by N-galactosylation of pyridones

Klegraf, Ellen,Follmann, Markus,Schollmeyer, Dieter,Kunz, Horst

, p. 3346 - 3360 (2004)

Stereoselective desymmetrization of 4-pyridone has been achieved through selective N-galactosylation, activation of the N-(galactosyl)pyridone by O-silylation and immediate addition of Grignard compounds. Chiral piperidine derivatives, e.g. (S)-(+)-coniine and (5S,9S)-(+)-indolozidine 167B, were synthesised in enantiomerically pure form using these highly regio- and stereoselective reactions. After N-galactosylation of 2-pyridone and O-silylation of the N-galactosyl-2-pyridone, addition of a Grignard compound proceeded with high 1,4-regioselectivity and complete diastereoselectivity, to furnish 4-substituted 5,6-dehydro-2-piperidones.
