Check Digit Verification of cas no

The CAS Registry Mumber 31334-51-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,3 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31334-51:
(7*3)+(6*1)+(5*3)+(4*3)+(3*4)+(2*5)+(1*1)=77
77 % 10 = 7
So 31334-51-7 is a valid CAS Registry Number.

TELOMERIZATION OF AMINO ACIDS WITH BUTADIENE, CATALYZED BY PALLADIUM COMPLEXES

Dzhemilev, U. M.,Fakhretdinov, R. N.,Telin, A. G.

, p. 1447 - 1456 (2007/10/02)

The telomerization of α, β, γ, and ε-amino acids having various structures with butadiene under the influence of the three-component palladium catalyst Pd(acac)2-PPh3-AlEt3 was investigated in DMSO-toluene solution.The α and ε-aliphatic and also the α, β, and γ-aromatic amino acids react with butadiene, giving the products from octadienylation at the amino group exclusively.Under the conditions of telomerization aliphatic β-amino acids are cleaved with the formation of unsaturated tertiary amines. in the case of aliphatic γ-amino acids it is possible to obtain telomers alkylated at the carbonyl group.
