Check Digit Verification of cas no

The CAS Registry Mumber 71000-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,0 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71000-20:
(7*7)+(6*1)+(5*0)+(4*0)+(3*0)+(2*2)+(1*0)=59
59 % 10 = 9
So 71000-20-9 is a valid CAS Registry Number.

HYDROLYSIS OF ESTERS OF N-RETINYLIDENEAMINO ACIDS

Karpenko, E. P.,Mitsner, B. I.,Zvonkova, E. N.,Evstigneeva, R. P.

, p. 1669 - 1673 (2007/10/02)

The hydrolysis rate of the ester bond in the molecules of methyl esters of the N-retinylidene derivatives of aliphatic amino acids depends on their chain lengths.The higher reaction rates for the derivatives of γ-aminobutyric and δ-aminovaleric acids are explained by intramolecular catalysis.
