Check Digit Verification of cas no

The CAS Registry Mumber 213689-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,6,8 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 213689-83:
(8*2)+(7*1)+(6*3)+(5*6)+(4*8)+(3*9)+(2*8)+(1*3)=149
149 % 10 = 9
So 213689-83-9 is a valid CAS Registry Number.

The enantioselective total synthesis of (-)-myltaylenol

Doye, Sven,Hotopp, Torsten,Wartchow, Rudolf,Winterfeldt, Ekkehard

, p. 1480 - 1488 (2007/10/03)

The unusual sesquiterpenoid alcohol (-)-myltaylenol (1) is synthesized by an intramolecular [4+2] cycloaddition of a chiral diene accessible from Hajos-Wiechert ketone by a sequence of reactions including stereoselective alkylation of an unsaturated ketone with thiophenylmethyl iodide as alkylation agent. As the link between diene and olefin a sulfonic ester group is used. The link permits control of the stereoselectivity of the [4+2] cycloaddition. After this key step the sulfonic ester group can be removed under oxidative conditions by molecular oxygen as oxidation agent, leading directly to a hydroxyketone that can be converted to (-)-myltaylenol by successive Shapiro reaction, regioselective hydroboration and Wittig reaction.
