204650-71-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204650-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,6,5 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 204650-71:
(8*2)+(7*0)+(6*4)+(5*6)+(4*5)+(3*0)+(2*7)+(1*1)=105
105 % 10 = 5
So 204650-71-5 is a valid CAS Registry Number.

Synthesis of the microbial elicitor syringolide 2 multiply labelled with deuterium
Henschke, Julian P.,Rickards, Rodney W.
, p. 211 - 220 (1998)
Multiply-deuterated syringolide 2 3 was prepared from D-xylulose and 8- bromooctanoic acid by a convergent route based on our previously reported biomimetic synthesis of this microbial elicitor. Key steps were the thermal acylation of the anisylidene-prot
