Check Digit Verification of cas no

The CAS Registry Mumber 141210-88-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,1 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 141210-88:
(8*1)+(7*4)+(6*1)+(5*2)+(4*1)+(3*0)+(2*8)+(1*8)=80
80 % 10 = 0
So 141210-88-0 is a valid CAS Registry Number.

LACTAM AND AMIDE ACETALS. 69. SYNTHESIS AND PROPERTIES OF 3-(AMINOMETHYLENE)-2-INDOLINONE DERIVATIVES

Golovko, T. V.,Solov'eva, N. P.,Bogdanova, G. A.,Sheinker, Yu. N.,Granik, V. G.

, p. 952 - 959 (2007/10/02)

Oxindole derivatives reacted with the diethyl acetals of dimethylformamide and dimethylacetamide to give the corresponding derivatives of 3-(aminomethylene)-, (aminoethylidene)-, and (ethoxyethylidene)-2-indolinone.These products were then easily converted to N-aryl- and N-alkylaminomethyleneoxindoles upon treatment with aryl or alkyl amines.The alkylation of N,N-dimethylaminomethylene-2-indolinones by dimethyl sulfate and triethyloxonium tetrafluoroborate, and the reactions of the resulting methyl sulfates and tetrafluoroborates with nucleophilic reagents were studied.The configuration of the 3-(aminomethylene)-2-indolinone derivatives prepared at the enamine C=C double bond was investigated by NMR.The free energies of activation for the cis-trans isomerization were determined in a number of cases.
