144367-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144367-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,6 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144367-89:
(8*1)+(7*4)+(6*4)+(5*3)+(4*6)+(3*7)+(2*8)+(1*9)=145
145 % 10 = 5
So 144367-89-5 is a valid CAS Registry Number.

The C4-Exo Methylene Isomer of Avermectin B1a: Synthesis via an Allylic Radical and Bioactivity
Fraser-Reid, Bert,Lopez, J. Cristobal,Faghih, Ramin
, p. 6763 - 6768 (2007/10/02)
Avermectin B1aΔ4,4a, 2, has been obtained from avermectin B1a, 1, and its bioactivity evaluated.The key step of the transformation is the reduction of an intermediate allylic radical with nBu3SnH.
