1233193-58-2 Usage
General Description
"(1R,3R,4S)-4-(tert-butyldiphenylsilyloxy)-2-Methylene-3-(trityloxyMethyl)cyclopentanol" is a complex organic compound that consists of multiple functional groups. These include a tert-butyldiphenylsilyloxy group, a methylene group and a trityloxyMethyl group, attached to a cyclopentanol ring. The compound is chiral, meaning it can't be superimposed onto its mirror image, and the descriptors (1R,3R,4S) tell us about the configuration of the different chiral centers in the molecule. The presence of silyloxy and trityl groups indicate its potential use as a protecting group in synthetic chemistry. However, as this is a typically industry-specific compound, further details about its use and properties would likely be proprietary to the chemist or company using it.
Check Digit Verification of cas no
The CAS Registry Mumber 1233193-58-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,1,9 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1233193-58:
(9*1)+(8*2)+(7*3)+(6*3)+(5*1)+(4*9)+(3*3)+(2*5)+(1*8)=132
132 % 10 = 2
So 1233193-58-2 is a valid CAS Registry Number.
