Selenocyanic acid, ethyl ester, also known as ethyl selenocyanoacetate, is an organoselenium compound with the chemical formula C4H7NOSe. It is a colorless liquid that is soluble in organic solvents and has a pungent odor. Selenocyanic acid, ethyl ester is synthesized by the reaction of ethyl bromoacetate with hydrogen selenide (H2Se) in the presence of a base, such as sodium hydroxide (NaOH). Ethyl selenocyanoacetate is primarily used as a reagent in organic synthesis, particularly in the preparation of various selenides and as a precursor for the synthesis of other organoselenium compounds. Due to its reactivity and potential toxicity, it should be handled with care and used in well-ventilated areas.

Check Digit Verification of cas no

The CAS Registry Mumber 3777-23-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,7 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3777-23:
(6*3)+(5*7)+(4*7)+(3*7)+(2*2)+(1*3)=109
109 % 10 = 9
So 3777-23-9 is a valid CAS Registry Number.
