165399-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 165399-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,3,9 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 165399-19:
(8*1)+(7*6)+(6*5)+(5*3)+(4*9)+(3*9)+(2*1)+(1*9)=169
169 % 10 = 9
So 165399-19-9 is a valid CAS Registry Number.

Stereocontrolled synthesis of (-)-allosamizoline using D-glucosamine as a chiral template
Takahashi, Shunya,Terayama, Hiroyuki,Kuzuhara, Hiroyoshi
, p. 5123 - 5126 (1991)
(-)-Allosamizoline (1), a core component of novel insect chitinase inhibitor, allosamidin (2), was stereoselectively synthesized from D-glucosamine (3), using an efficient ring contraction reaction as a key step.
