Check Digit Verification of cas no

The CAS Registry Mumber 183293-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,2,9 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 183293-43:
(8*1)+(7*8)+(6*3)+(5*2)+(4*9)+(3*3)+(2*4)+(1*3)=148
148 % 10 = 8
So 183293-43-8 is a valid CAS Registry Number.

Total synthesis of 10-deoxymethynolide, the aglycon of the macrolide antibiotic 10-deoxymethymycin

Pilli, Ronaldo A.,De Andrade, Carlos Kleber Z.,Souto, Carlos Roberto O.,De Meijere, Armin

, p. 7811 - 7819 (2007/10/03)

A short efficient total synthesis of 10-deoxymethynolide (2c), the aglycon of 10-deoxymethymycin (1c), has been accomplished in 16 steps and 12% overall yield from (S)-3-O-p-toluenesulfonyl-3-hydroxy-2-methylpropanal (15c). The synthesis features an expeditious preparation of (+)-5a, a synthetic equivalent of the Prelog-Djerassi lactonic acid, and the construction of a 12-membered lactone through an intramolecular Nozaki- Hiyama-Kishi coupling reaction.
