290838-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 290838-42-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,8,3 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 290838-42:
(8*2)+(7*9)+(6*0)+(5*8)+(4*3)+(3*8)+(2*4)+(1*2)=165
165 % 10 = 5
So 290838-42-5 is a valid CAS Registry Number.

Desymmetrization of aziridine with malononitrile using cinchona alkaloid amide/zinc(ii) catalysts

Shiomi, Noriyuki,Kuroda, Mami,Nakamura, Shuichi

, p. 1817 - 1820 (2017)

The catalytic enantioselective desymmetrization of aziridines with malononitrile has been developed. Good yield and enantioselectivity were obtained by using cinchona alkaloid amide/Zn(ii) catalysts. The obtained product can be converted to β-aminoester,

Synthesis of Cyclic β-Amino Acid Esters from Methionine, Allylglycine, and Serine

Gardiner, James,Anderson, Kelly H.,Downard, Alison,Abell, Andrew D.

, p. 3375 - 3382 (2007/10/03)

Here we report a versatile ring-closing metathesis-based approach to 5-, 6-, and 7-membered cyclic β-amino esters starting with simple and readily available building blocks-methionine, allylglycine, and serine-where the nature of the amino acid determines
