Check Digit Verification of cas no
The CAS Registry Mumber 162887-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,8,8 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 162887-23:
(8*1)+(7*6)+(6*2)+(5*8)+(4*8)+(3*7)+(2*2)+(1*3)=162
162 % 10 = 2
So 162887-23-2 is a valid CAS Registry Number.

Paragraph 0006, (2018/04/01)
The present invention relates to the field of medicine preparation, particularly to the field of biapenem side chains. According to the present invention, the ertapenem side chain belongs to a medicine preparation raw material, and can be used for producing ertapenem antibiotic drugs; ertapenem is a novel carbapenem-based antibiotic, and can be combined with penicillin-binding protein so as to interfere the synthesis of bacterial cell walls and cause the inhibition on bacterial growth and reproduction, wherein a small amount of cell lysis can be generated; and the product can provide high antibacterial activity on methicillin-sensitive Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes and other Gram-positive bacteria, and Enterobacteriaceae bacteria, and is highly sensitive to Haemophilus, Moraxelle catarrhalis, Neisseria meningitidis and the like, and methicillin-resistant Staphylococcus, Enterococcus, Pseudomonas aeruginosa, Acinetobacter and other bacteria resist the product.
