165674-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 165674-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,6,7 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 165674-73:
(8*1)+(7*6)+(6*5)+(5*6)+(4*7)+(3*4)+(2*7)+(1*3)=167
167 % 10 = 7
So 165674-73-7 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
