(1RS,2SR,3SR)-o-menthan-3-ol, also known as (+)-menthol, is a naturally occurring monoterpene alcohol derived from the essential oil of peppermint (Mentha × piperita). It is a chiral molecule with three asymmetric carbon centers, resulting in eight possible stereoisomers. This specific isomer is characterized by its (1RS,2SR,3SR) configuration, which gives it a strong cooling sensation when applied to the skin. Menthol is widely used in various applications, including pharmaceuticals, cosmetics, and food products, due to its analgesic, anti-itch, and flavor-enhancing properties. It is also known for its ability to provide a refreshing and invigorating effect, making it a popular ingredient in oral care and topical products.
The CAS Registry Mumber 15358-76-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,3,5 and 8 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 15358-76: (7*1)+(6*5)+(5*3)+(4*5)+(3*8)+(2*7)+(1*6)=116 116 % 10 = 6 So 15358-76-6 is a valid CAS Registry Number.
