106851-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106851-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,8,5 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 106851-55:
(8*1)+(7*0)+(6*6)+(5*8)+(4*5)+(3*1)+(2*5)+(1*5)=122
122 % 10 = 2
So 106851-55-2 is a valid CAS Registry Number.

, 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
