Check Digit Verification of cas no

The CAS Registry Mumber 80595-16-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,9 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80595-16:
(7*8)+(6*0)+(5*5)+(4*9)+(3*5)+(2*1)+(1*6)=140
140 % 10 = 0
So 80595-16-0 is a valid CAS Registry Number.

Synthesis, biological, and chiroptical activity of 3-phenyl-clavams

Cierpucha, Maciej,Solecka, Jolanta,Frelek, Jadwiga,Szczukiewicz, Patrycja,Chmielewski, Marek

, p. 405 - 416 (2007/10/03)

The [2+2]cycloaddition of chlorosulfonyl isocyanate to simple vinyl ethers derived from the 2-O-sulfonylated (R) and (S) 1-phenyl-1,2-ethanediol leads to 4-alkoxy-azetidin-2-ones with a moderate stereoselectivity. The cycloaddition to analogous (Z)-propenyl ethers proceeds stereospecifically with the retention of the olefin configuration. The intramolecular alkylation of β-lactam nitrogen atom furnished all possible stereoisomers of 3-phenyl- and 6-methyl-3-phenyl-clavams. The biological and chiroptical activity of synthesized clavams was investigated. The (3R,5R)-diastereomer 30 showed higher inhibition of bacterial enzymes than other related compounds.
