Triethylphosphine-carbon disulfide adduct, also known as triethylphosphine carbon disulfide or P(C2H5)3-CS2, is a chemical compound formed by the reaction of triethylphosphine (P(C2H5)3) and carbon disulfide (CS2). This adduct is a colorless liquid with a pungent odor and is used as a reagent in various chemical reactions, particularly in the synthesis of organophosphorus compounds. It is also employed as a ligand in coordination chemistry and as a stabilizing agent in the production of certain organometallic compounds. The compound is sensitive to air and moisture, and it should be stored under an inert atmosphere to prevent decomposition.

Check Digit Verification of cas no

The CAS Registry Mumber 997-47-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 997-47:
(5*9)+(4*9)+(3*7)+(2*4)+(1*7)=117
117 % 10 = 7
So 997-47-7 is a valid CAS Registry Number.
