Check Digit Verification of cas no
The CAS Registry Mumber 31007-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,0 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31007-03:
(7*3)+(6*1)+(5*0)+(4*0)+(3*7)+(2*0)+(1*3)=51
51 % 10 = 1
So 31007-03-1 is a valid CAS Registry Number.

, p. 1006 - 1009 (2007/10/02)
Grignard reaction followed by ozonolysis, or ozonolysis followed by Grignard reaction on the pentanoate 8, generates the diol 9.Cyclodehydration of 9 leads to the 3-oxacuparene (6), whereas PCC oxidation furnishes the 3-oxa-β-cuparenone (7).Methanesulfoni
