Check Digit Verification of cas no

The CAS Registry Mumber 1358742-31-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,8,7,4 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1358742-31:
(9*1)+(8*3)+(7*5)+(6*8)+(5*7)+(4*4)+(3*2)+(2*3)+(1*1)=180
180 % 10 = 0
So 1358742-31-0 is a valid CAS Registry Number.

Synthesis of amino acid derived imidazolidinium salts as new NHC precatalysts

Strand, Ragnhild B.,Helgerud, Trygve,Solvang, Tina,Sperger, Christian A.,Fiksdahl, Anne

, p. 1994 - 2006 (2012/03/22)

The preparation of new chiral symmetrically and unsymmetrically N,N′-disubstituted imidazolium based NHC salts Ib, IIb, IIIa-c and IVc-h from the amino acids l-proline and l-phenylalanine, is reported. Some preliminary tests have been carried out, demonstrating that the chiral NHCs give chiral induction in organometallic catalysis and can be used as organocatalysts.
