134040-02-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134040-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,0,4 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134040-02:
(8*1)+(7*3)+(6*4)+(5*0)+(4*4)+(3*0)+(2*0)+(1*2)=71
71 % 10 = 1
So 134040-02-1 is a valid CAS Registry Number.

Synthesis of β-hydroxypiperidine alkaloids by anodic oxidation of carbamates and hydroboration
Plehiers, Mark,Hootelé, Claude
, p. 2444 - 2453 (2007/10/03)
The β-hydroxypiperidine alkaloids (±)-pseudoconhydrine, (±)-N-methylpseudoconhydrine, (-)-5-hydroxysedamine, and (+)-sedacryptine were synthesized. Successive functionalization of the piperidine ring via anodic methoxylation allowed the regio- and stereos
