Nonoxynol-9 (N-9) is a typical surfactant used as a vaginal spermicide. Spermicides are locally acting non-hormonal contraceptives. When present in the vagina during intercourse, they immobilize/inactivate/damage and/or kill sperms without eliciting systemic effects. N-9 has been in use for more than 30 years as an over-the-counter (OTC) drug in creams, gels, foams and condom lubricants. It is the most commonly used spermicidal contraceptive in the UK and the USA. In several European countries, spermicides are no longer on the market.

Uses

Nonoxynol 9 is a reagent used to prepare compounds that show spermacidal activity. It is also a polyoxyethylene surfactant that shows toxicity to certain wildlife. Ranges from 5-15 ethyleneoxy moiety.

Definition

ChEBI: Nonoxynol 9 is a tergitol polymer consisting of nonylbenzene with a nine-membered poly(ethylene glycol) moiety attached at position 4. It has a role as a nonionic surfactant and a contraceptive drug.

Brand name

Conceptrol (Ortho Pharmaceutical); Emko (Schering-Plough HealthCare); Gynol II (Ortho Pharmaceutical); Intercept (Ortho Pharmaceutical); Semicid (Whitehall-Robins); Today Sponge (Whitehall-Robins).

Check Digit Verification of cas no

The CAS Registry Mumber 14409-72-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,4,0 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 14409-72:
(7*1)+(6*4)+(5*4)+(4*0)+(3*9)+(2*7)+(1*2)=94
94 % 10 = 4
So 14409-72-4 is a valid CAS Registry Number.
