The chemical compound "((2R,3S)-2-Ethoxyoxalylsulfanyl-3-ethyl-4-oxo-azetidin-1-yl)-(triphenyl-λ5-phosphanylidene)-acetic acid 4-nitro-benzyl ester" is a complex organic molecule with a unique structure. It features a 4-nitro-benzyl ester group attached to an acetic acid moiety, which is further connected to a phosphanylidene group. The phosphanylidene is part of a triphenyl-λ5-phosphane, indicating a phosphorus atom bonded to three phenyl rings. The azetidinone ring, which is a four-membered ring with one nitrogen atom, has a 2-ethoxyoxalylsulfanyl and a 3-ethyl substituent, with the stereochemistry at these positions being (2R,3S). ((2R,3S)-2-Ethoxyoxalylsulfanyl-3-ethyl-4-oxo-azetidin-1-yl)-(triphenyl-λ5-phosphanylidene)-acetic acid 4-nitro-benzyl ester is likely to be of interest in the field of organic chemistry, potentially for its reactivity or as a building block in the synthesis of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 78032-30-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,3 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78032-30:
(7*7)+(6*8)+(5*0)+(4*3)+(3*2)+(2*3)+(1*0)=121
121 % 10 = 1
So 78032-30-1 is a valid CAS Registry Number.
