142763-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142763-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,6 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142763-03:
(8*1)+(7*4)+(6*2)+(5*7)+(4*6)+(3*3)+(2*0)+(1*3)=119
119 % 10 = 9
So 142763-03-9 is a valid CAS Registry Number.

Total Synthesis of (+/-)-Velloziolone
Snider, Barry B.,Buckman, Brad O.
, p. 4883 - 4888 (2007/10/02)
The first total synthesis of the 9,10-seco-kaurene velloziolone (3) has been accomplished using an atom transfer tandem free-radical cyclization to prepare the 6-methylenebicyclooctan-2-one moiety.The known diol 11 is converted to iodo acetate 10 i
