Check Digit Verification of cas no
The CAS Registry Mumber 20945-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,4 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20945-52:
(7*2)+(6*0)+(5*9)+(4*4)+(3*5)+(2*5)+(1*2)=102
102 % 10 = 2
So 20945-52-2 is a valid CAS Registry Number.

Method for preparing (R)-selenomethylselenocysteine
-
Paragraph 0032; 0034, (2020/02/08)
The invention discloses a method for preparing (R)-selenomethylselenocysteine. The method comprises: preparing (3S,6S)-3,6-dichloromethyl-2,5-diketopiperazine; in a nitrogen atmosphere, carrying out areaction on sodium borohydride and dimethyl diselenide by using an alcohol as a solvent to generate sodium methyl selenol; carrying out a reaction on the sodium methyl selenol and the (3S,6S)-3,6-dichloromethyl-2,5-diketopiperazine to generate (3S,6S)-3,6-dimethylselenomethyl-2,5-diketopiperazine; and finally hydrolyzing the (3S,6S)-3,6-dimethylselenomethyl-2,5-diketopiperazine to generate (R)-selenomethylselenocysteine. According to the invention, the method has advantages of easily available and cheap raw materials, convenient operation, mild reaction conditions, easy product separation andhigh yield, and is suitable for industrial production.
