100780-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100780-45-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,7,8 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 100780-45:
(8*1)+(7*0)+(6*0)+(5*7)+(4*8)+(3*0)+(2*4)+(1*5)=88
88 % 10 = 8
So 100780-45-8 is a valid CAS Registry Number.

A New Synthesis of Pyrroles from Nitroalkenes
Barton, Derek H. R.,Zard, Samir Z.
, p. 1098 - 1100 (2007/10/02)
Nitroalkenes, or their β-acetoxynitro precursors, react with α-isocyanoacetate esters in the presence of base to give high yields of 5-unsubstituted pyrroles; some important pyrroles are easily synthesised by this method.
