139356-37-9 Usage

General Description

2-((3R,5R)-3,5-bis(tert-butyldimethylsilyloxy)cyclohexylidene)ethanol is a chemical compound with the molecular formula C20H42O3Si2. It is a derivative of cyclohexylidene ethanol and contains two tert-butyldimethylsilyloxy groups attached to the cyclohexylidene ring. 2-((3R,5R)-3,5-bis(tert-butyldiMethylsilyloxy)cyclohexylidene)ethanol is commonly used in organic synthesis as a protecting group for alcohols, as the tert-butyldimethylsilyloxy groups can be easily removed under mild conditions to reveal the free hydroxyl group. Additionally, this compound has potential applications in the pharmaceutical industry and in the development of new materials due to its unique structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 139356-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,5 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139356-37:
(8*1)+(7*3)+(6*9)+(5*3)+(4*5)+(3*6)+(2*3)+(1*7)=149
149 % 10 = 9
So 139356-37-9 is a valid CAS Registry Number.
