102870-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102870-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,8,7 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102870-49:
(8*1)+(7*0)+(6*2)+(5*8)+(4*7)+(3*0)+(2*4)+(1*9)=105
105 % 10 = 5
So 102870-49-5 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
