Check Digit Verification of cas no
The CAS Registry Mumber 90407-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,0 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90407-14:
(7*9)+(6*0)+(5*4)+(4*0)+(3*7)+(2*1)+(1*4)=110
110 % 10 = 0
So 90407-14-0 is a valid CAS Registry Number.

Benzothiophenes are formed with yields of more than 77percent in a single preparative stage during the gas-phase reaction of halogenoarenes with hydrogen sulfide and acetylene (600-700 deg C).It is suggested that arylthiyl radicals (ArS-radical), which are effectively captured by the acetylene, participate in the process.The effect of the structure of the halogenoarene on the selectivity of the process is discussed.The gas-phase reaction of 2-chlorothiophene with hydrogen sulfide in the presence of acetylene leads to the formation of thienothiophene.
