1118905-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1118905-18-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,8,9,0 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1118905-18:
(9*1)+(8*1)+(7*1)+(6*8)+(5*9)+(4*0)+(3*5)+(2*1)+(1*8)=142
142 % 10 = 2
So 1118905-18-2 is a valid CAS Registry Number.

Metal-Free Oxidative Cross-Coupling Reaction of Thiophene Iodonium Salts with Pyrroles
Morimoto, Koji,Nakamura, Akira,Dohi, Toshifumi,Kita, Yasuyuki
, p. 4294 - 4297 (2016)
The hypervalent-iodine-mediated oxidative metal-free cross-coupling reaction of thiophenes with various pyrroles was developed. The corresponding thiophene–pyrrole derivatives were obtained in moderate to high yields (up to 85 %). This method features hig
