Check Digit Verification of cas no

The CAS Registry Mumber 109576-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,7 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109576-85:
(8*1)+(7*0)+(6*9)+(5*5)+(4*7)+(3*6)+(2*8)+(1*5)=154
154 % 10 = 4
So 109576-85-4 is a valid CAS Registry Number.

KINETICS OF CYCLOADDITION OF MELEIC ANHYDRIDE TO ARYLAMINOMETHYLENE DERIVATIVES OF 1-PHENYL-3-METHYL-5-PYRAZOLESELENONE

Potapochkina, I. I.,Kvitko, I. Ya.,Koldobskii, G. I.

, p. 2126 - 2130 (2007/10/02)

The kinetics of the cycloaddition of maleic anhydride to the arylaminomethylene derivatives of 1-phenyl-3-methyl-5-pyrazoleselenone at 30-60 deg C were studied.The effect of a substituent in the phenyl ring of the aminomethylene fragment is described by the ?0 constants.The effect of the solvent on the reaction is small.Substitution of a sulfur atom at position 5 of the heterocycle by the selenium atom increases the cycloaddition rate by several times.
