931405-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 931405-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,1,4,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 931405-40:
(8*9)+(7*3)+(6*1)+(5*4)+(4*0)+(3*5)+(2*4)+(1*0)=142
142 % 10 = 2
So 931405-40-2 is a valid CAS Registry Number.

, p. 3380 - 3385 (2007/10/03)
(+)-Carpamic acid [(2′R,5′S,6′S)-8-(5′-hydroxy-6′-methylpiperidin-2′-yl)octanoic acid, 1] was synthesized from (S)-alanine, employing intramolecular and reductive amination of acyclic amino ketone 8 as the key step to generate the piperidine ring.
