Check Digit Verification of cas no

The CAS Registry Mumber 74911-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,1 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74911-90:
(7*7)+(6*4)+(5*9)+(4*1)+(3*1)+(2*9)+(1*0)=143
143 % 10 = 3
So 74911-90-3 is a valid CAS Registry Number.

Synthese von (+)-Aspicilin mit Bausteinen aus nachwachsenden Rohstoffen

Quinkert, Gerhard,Fernholz, Erhard,Eckes, Peter,Neumann, Doris,Duerner, Gerd

, p. 1753 - 1786 (2007/10/02)

The 18-membered lichen macrolide (+)-aspicilin (1) is easily built up from compounds 14, 16, 3, and 24 following the C3 + C7 + C6 +C2 = C18 pattern (see Schemes).The synthesis requires 15 steps and gives 1 in 13percent overall yield from D-mannose (2).The

Synthese totale des acides (+) et (-) nonactique a partir de carbohydrates

Ireland, Robert E.,Vevert, Jean-Paul

, p. 572 - 583 (2007/10/02)

The synthesis of (-) and (+) nonactic acids (2a) and (2b) has been achieved starting from D-mannose (7) and D-gluono-γ-lactone (22) respectively.The key step in the synthesis is the -sigmatropic rearrangement of the silylated ketene-acetals IV leadin
