(+/-)-Toluene-4-sulfonic acid-(trans-2-deuterio-cyclohexyl ester) is a complex organic compound that consists of a toluene-4-sulfonic acid moiety and a trans-2-deuterio-cyclohexyl ester group. (+/-)-toluene-4-sulfonic acid-(trans-2-deuterio-cyclohexyl ester) is characterized by the presence of a deuterium atom (a stable isotope of hydrogen) in the trans-2 position of the cyclohexyl ring, which may affect its chemical properties and reactivity compared to the non-deuterated version. The toluene-4-sulfonic acid part of the molecule contains a sulfonic acid group attached to the para position of a toluene ring, which imparts acidic properties. The ester linkage between the sulfonic acid and the cyclohexyl group suggests that (+/-)-toluene-4-sulfonic acid-(trans-2-deuterio-cyclohexyl ester) could be involved in various chemical reactions, such as hydrolysis, where the ester bond is broken to release the acid and the alcohol. Such compounds are often used in organic synthesis, as intermediates in the preparation of pharmaceuticals, or as reagents in chemical transformations due to their unique structural features and potential to influence reaction outcomes.

Check Digit Verification of cas no

The CAS Registry Mumber 957-28-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 957-28:
(5*9)+(4*5)+(3*7)+(2*2)+(1*8)=98
98 % 10 = 8
So 957-28-8 is a valid CAS Registry Number.
