110919-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110919-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,9,1 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 110919-02:
(8*1)+(7*1)+(6*0)+(5*9)+(4*1)+(3*9)+(2*0)+(1*2)=93
93 % 10 = 3
So 110919-02-3 is a valid CAS Registry Number.

A STEREOSELECTIVE APPROACH TO 1β-METHYLCARBAPENEM ANTIBIOTIC STARTING FROM (R)-(-)-3-HYDROXYBUTYRIC ACID ESTER
Hatanaka, Minoru
, p. 83 - 86 (2007/10/02)
The chiral key intermediate of 1β-methylcarbapenem antibiotic is synthesized via (2R,3R,4S,5R)-3-amino-2,5-dimethyl-5-pentanolide-4-carboxylic acid, which is prepared in a stereoselective manner from (R)-(-)-hydroxy-butyrate.
