α-Phenylsulfonyl-3,5-dimethoxycinnamonitrile is a complex organic chemical compound characterized by its molecular formula C16H15NO3S. α-phenylsulfonyl-3,5-dimethoxycinnamonitrile features a phenylsulfonyl group attached to a cinnamate backbone, which is further substituted with two methoxy groups at the 3rd and 5th positions. The nitrile functional group is present at the end of the cinnamate chain, contributing to its reactivity and potential applications in chemical synthesis. It is a colorless to pale yellow solid and is typically used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique structural features and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 25303-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,0 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25303-98:
(7*2)+(6*5)+(5*3)+(4*0)+(3*3)+(2*9)+(1*8)=94
94 % 10 = 4
So 25303-98-4 is a valid CAS Registry Number.

Organocatalytic domino reaction of cyanosulfones: Access to complex cyclohexane systems with quaternary carbon centers

Rajkumar, Sundaram,Shankland, Kenneth,Goodman, Jonathan M.,Cobb, Alexander J. A.

, p. 1386 - 1389 (2013)

When ε-nitro-α,β-unsaturated esters are added to conjugated cyanosulfones in the presence of a bifunctional thiourea catalyst, a highly stereoselective domino reaction occurs to generate complex cyclohexanes with up to four stereogenic centers, one of whi
