Cis-2-methylcyclopentyl p-toluenesulfonate is a chemical compound with the molecular formula C12H16O3S. It is a derivative of cyclopentyl p-toluenesulfonate, featuring a methyl group attached to the second carbon atom in the cyclopentyl ring. This organic compound is known for its potential use as a chiral auxiliary in asymmetric synthesis, which can help in the creation of enantiomerically pure compounds. The cis-configuration indicates that the methyl group and the p-toluenesulfonate group are on the same side of the cyclopentyl ring. cis-2-methylcyclopentyl p-toluenesulfonate is also recognized for its role in certain chemical reactions, such as in the synthesis of complex organic molecules, where its stereochemistry can influence the outcome of the reaction.

Check Digit Verification of cas no

The CAS Registry Mumber 5857-77-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5857-77:
(6*5)+(5*8)+(4*5)+(3*7)+(2*7)+(1*7)=132
132 % 10 = 2
So 5857-77-2 is a valid CAS Registry Number.
