Check Digit Verification of cas no

The CAS Registry Mumber 1000387-95-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,3,8 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1000387-95:
(9*1)+(8*0)+(7*0)+(6*0)+(5*3)+(4*8)+(3*7)+(2*9)+(1*5)=100
100 % 10 = 0
So 1000387-95-0 is a valid CAS Registry Number.

Chemoselective and stereoselective synthesis of gem-difluoro-β-aminoesters or gem-difluoro-β-lactams from ethylbromodifluoroacetate and imines during Reformatsky reaction

Boyer, Nicolas,Gloanec, Philippe,De Nanteuil, Guillaume,Jubault, Philippe,Quirion, Jean-Charles

, p. 12352 - 12366 (2007)

The chemoselective and stereoselective synthesis of gem-difluoro-β-aminoesters or gem-difluoro-β-lactams was investigated from ethylbromodifluoroacetate and imines during Reformatsky reaction. Influence of various reaction parameters, such as nature of the amine part, nature of the chiral auxiliary, was evaluated. High levels of stereoselectivity (up to 98%) were obtained for gem-difluoro-β-aminoesters and gem-difluoro-β-lactams using either (R)-phenylglycinol or (R)-methoxyphenylglycinol.
