94033-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94033-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,0,3 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94033-70:
(7*9)+(6*4)+(5*0)+(4*3)+(3*3)+(2*7)+(1*0)=122
122 % 10 = 2
So 94033-70-2 is a valid CAS Registry Number.

Sulfur Derivatives of 1-Methylpyrrole
Gronowitz, Salo,Kada, Rudolf
, p. 1041 - 1043 (2007/10/02)
Metalation of 1-methylpyrrole using n-butyllithium and tetramethylethylenediamine (TMEDA) in ether furnished 1-methyl-2-pyrrolylithium, which in turn was converted to 1-methyl-2-methylthiopyrrole upon treatment with dimethyldisulfide.Further formylation w
