67845-89-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67845-89-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,4 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 67845-89:
(7*6)+(6*7)+(5*8)+(4*4)+(3*5)+(2*8)+(1*9)=180
180 % 10 = 0
So 67845-89-0 is a valid CAS Registry Number.

Synthesis of 2,2,6,6-tetramethylpiperidine derivatives
Kashparova,Kagan,Kashparov,Zhukova
, p. 667 - 668 (2007/10/03)
Diazotization of 4-amino-2,2,6,6-tetramethylpiperidine in acetic or sulfuric acid affords 2,2,6,6-tetramethyl-1,2,3,6-tetrahydropyridine in high yield. Under the same conditions, the corresponding nitroxyl radical transforms into 4-hydroxy-2,2,6,6-tetrame
