1269439-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1269439-28-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,4,3 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1269439-28:
(9*1)+(8*2)+(7*6)+(6*9)+(5*4)+(4*3)+(3*9)+(2*2)+(1*8)=192
192 % 10 = 2
So 1269439-28-2 is a valid CAS Registry Number.

Synthesis of polyhydroxy 7- and N-alkyl-azepanes as potent glycosidase inhibitors
Shih, Tzenge-Lien,Liang, Ming-Tsung,Wu, Kuen-Da,Lin, Chun-Hung
, p. 183 - 190 (2011)
An effective synthetic method for polyhydroxylated azepanes that contain an alkyl group (Me or Bu) at either the 7- or N-positions is developed. The synthetic routes are accomplished in eight to ten steps from d-(-)-quinic acid. Among the compounds synthe
