83576-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83576-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,7 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83576-25:
(7*8)+(6*3)+(5*5)+(4*7)+(3*6)+(2*2)+(1*5)=154
154 % 10 = 4
So 83576-25-4 is a valid CAS Registry Number.

A New Synthesis of Imidazoles
Casey, Michael,Moody, Christopher J.,Rees, Charles W.
, p. 714 - 715 (2007/10/02)
Alkenes are converted into imidazoles through their epoxides by treatment with 2-tri-n-butylstannyltetrazoles (2), followed by dehydration with methyltriphenoxyphosphonium iodide in an improved procedure, and photolysis of the resulting vinyltetrazoles (4).
