Check Digit Verification of cas no

The CAS Registry Mumber 91598-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,9 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91598-89:
(7*9)+(6*1)+(5*5)+(4*9)+(3*8)+(2*8)+(1*9)=179
179 % 10 = 9
So 91598-89-9 is a valid CAS Registry Number.

MACROHETEROCYCLES. XVII. SYNTHESIS AND ENANTIOSELECTIVE CHARACTERISTICS OF CHIRAL N,N'-DIACYLDIAZA-18-CROWN-ETHERS

Luk'yanenko, N. G.,Bogat-skii, A. V.,Basok, S. S.,Ostrovskaya, L. K.,Nazarova, N. Yu.,Karpenko, L. P.

, p. 1438 - 1444 (2007/10/02)

N,N'-Diacyldiaza-18-crown-6 ethers were obtained by the acylation of diaza-18-crown-6 with amino acids.The enantioselectivity coefficients were determined for the chiral compound in relation to the L and D isomers of valine.The obtained compounds represent a promising class of enantioselective complexones.
