122648-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122648-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,6,4 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122648-69:
(8*1)+(7*2)+(6*2)+(5*6)+(4*4)+(3*8)+(2*6)+(1*9)=125
125 % 10 = 5
So 122648-69-5 is a valid CAS Registry Number.

Chemical delivery systems for some penicillinase-resistant semisynthetic penicillins
Pop,Wu,Bodor
, p. 1789 - 1795 (2007/10/02)
Chemical delivery systems (CDS's) based on a dihydropyridine ? quaternary pyridinium ion redox system analogous to the naturally occurring NADH ? NAD+ system were synthesized for a group of staphylococcal penicillinase resistant penicillins, in
