98376-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98376-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,7 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98376-31:
(7*9)+(6*8)+(5*3)+(4*7)+(3*6)+(2*3)+(1*1)=179
179 % 10 = 9
So 98376-31-9 is a valid CAS Registry Number.

SYNTHESIS OF 3-AMINOALKYL SUBSTITUTED CARBAPENEMS VIA A PHOSPHORANE INTERMEDIATE
Vries, Johannes G. de,Gerhard, Sigmund
, p. 2765 - 2768 (2007/10/02)
Reaction of azetidinone phosphoranes 1 with aldehyde 8 gave the olefins 4, which were converted into carbapenem esters 6 in 4 steps.Hydrogenation of 6 gave the title compounds.
