338800-72-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 338800-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,8,8,0 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 338800-72:
(8*3)+(7*3)+(6*8)+(5*8)+(4*0)+(3*0)+(2*7)+(1*2)=149
149 % 10 = 9
So 338800-72-9 is a valid CAS Registry Number.

Synthesis and structure of chiral silatranes derived from terpenes

Wagner, Gabriele,Herrmann, Rudolf,Pedersen, Bj?rn,Scherer, Wolfgang

, p. 25 - 38 (2007/10/03)

Starting with the chiral pool compounds (-)-menthone, (-)-limonene, (-)-β-pinene, and (-)-carvone, new homochiral triethanolamine derivatives were obtained and converted to chiral silatranes. These silatraries were characterized by crystal structure analyses and NMR techniques. Conformational analyses in the solid state and in solution show that the chiral terpene residues determine the direction of the ring puckering of the silatrane moiety.
