4-Phenoxy-1-(p-toluolsulfonyloxy)-cis-penten-2 is a complex organic chemical compound with the molecular formula C18H20O4S. It is characterized by a cis-penten-2 backbone, which features a double bond between the second and third carbon atoms. The molecule also contains a phenoxy group attached to the fourth carbon, and a p-toluolsulfonyloxy group attached to the first carbon. The p-toluolsulfonyloxy group is a derivative of toluene, where a sulfonyl group (-SO2-) replaces one of the hydrogen atoms on the methyl group. 4-Phenoxy-1-(p-toluolsulfonyloxy)-cis-penten-2 is likely to be used in the synthesis of more complex organic molecules, potentially in pharmaceuticals or other specialty chemicals, due to its unique structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 1235-91-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1235-91:
(6*1)+(5*2)+(4*3)+(3*5)+(2*9)+(1*1)=62
62 % 10 = 2
So 1235-91-2 is a valid CAS Registry Number.
