85768-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85768-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,6 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85768-34:
(7*8)+(6*5)+(5*7)+(4*6)+(3*8)+(2*3)+(1*4)=179
179 % 10 = 9
So 85768-34-9 is a valid CAS Registry Number.

Stereoselective Synthesis of a (5R,6S)-6--2-aryloxypenem
Cooke, Michael D.,Moore, Kevin W.,Ross, Barry C.,Turner, Susan E.
, p. 1005 - 1006 (2007/10/02)
(5R,6S)--2-aryloxypenems can be synthesised through hydroxy group directed chlorinolysis of the (3S,4R)-3--4-ethylthioazetidinone (8) to the (4S)-4-chloroazetidinone (9) with subsequent cyclisation.
