144989-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144989-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,8 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144989-63:
(8*1)+(7*4)+(6*4)+(5*9)+(4*8)+(3*9)+(2*6)+(1*3)=179
179 % 10 = 9
So 144989-63-9 is a valid CAS Registry Number.

Simpkins, Nigel S.,Stokes, Stephen,Whittle, Alan J.
, p. 2471 - 2478 (2007/10/02)
An enantiospecific synthesis of allosamizoline 4, the aglycone of the chitinase inhibitor allosamidin 3, has been achieved, starting from readily available glucosamine.The key step in the synthesis involves the cyclisation of a carbon-centred radical onto
