301857-39-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 301857-39-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,1,8,5 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 301857-39:
(8*3)+(7*0)+(6*1)+(5*8)+(4*5)+(3*7)+(2*3)+(1*9)=126
126 % 10 = 6
So 301857-39-6 is a valid CAS Registry Number.

Unexpected reactivity of imidazo[2,1-b]thiazolines with organometallic reagents
Sisko, Joseph,Kassick, Andrew J.,Shetzline, Steven B.
, p. 2877 - 2880 (2000)
The reaction of imidazo[2,1-b]thiazolines with various organometallic reagents is described. Nucleophilic attack of organolithium reagents on sulfur occurs with extrusion of ethylene to produce 2-thioalkyl-or 2-thioarylimidazoles. The outcome with Grignar
