107728-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107728-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,7,2 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107728-99:
(8*1)+(7*0)+(6*7)+(5*7)+(4*2)+(3*8)+(2*9)+(1*9)=144
144 % 10 = 4
So 107728-99-4 is a valid CAS Registry Number.

By means of sodium/tert-butyl alcohol 4,5-dichlorotricyclo2,7>hept-3-ene (7b) was transformed to unsubstituted homobenzvalene (1), which can thus be obtained in three steps from benzvalene with 45percent yield. Homobenzvalene (1
