106183-49-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106183-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,1,8 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106183-49:
(8*1)+(7*0)+(6*6)+(5*1)+(4*8)+(3*3)+(2*4)+(1*9)=107
107 % 10 = 7
So 106183-49-7 is a valid CAS Registry Number.

Potentially Aromatic Thiophenium Ylides 3. Cyclization of 2-(2'-Thienyl)benzoylcarbene
Storflor, Harry,Skramstad, Jan
, p. 178 - 183 (2007/10/02)
Catalytic decomposition of 2(2'-diazoacetylphenyl)thiophene gives the 4,10b-dihydro-indacyclopropathiophen-6-one (5) and the naphthothiophen-5-ol (6).It is shown that 5 rearranges to 6 under acid catalysis.The mechanisms for the r
