349132-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 349132-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,1,3 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 349132-18:
(8*3)+(7*4)+(6*9)+(5*1)+(4*3)+(3*2)+(2*1)+(1*8)=139
139 % 10 = 9
So 349132-18-9 is a valid CAS Registry Number.

Stereocontrolled chemoenzymatic synthesis of 2,3-disubstituted piperidines
Monterde, Maria I.,Brieva, Rosario,Gotor, Vicente
, p. 525 - 528 (2007/10/03)
(R,R)-2,3-Disubstituted piperidines were readily synthesized starting from (R)-(+)-5-bromo-2-hydroxypentanenitrile (R)-2. An enantioselective (R)-oxynitrilase-catalyzed transcyanation was used to prepare the starting cyanohydrin (R)-2.
